I think all that needs to happen is for the Catholic clergy of Rome to meet and elect a new pope.  Even if there are only a handful of Catholic clergy left in Rome.  And although it would be more difficult to do, I think a general council of the Catholic bishops of the whole world could also credibly elect a true pope.

There are to be called to the General Council the following persons who shall have a decisive vote:
 
1. The Cardinals of the Holy Roman Church, even those who are not bishops.
2. The patriarchs, primates, archbishops, residential bishops, even those not yet consecrated.
3. The abbots and prelates nullius.
4. The abbot Primas, abbots who are superiors of Monastic Congregations, and the supreme heads of clerical exempt Orders of religious. The superiors general of other religious bodies are not to be called, unless the bull of convocation explicitly states that they are to be called. If titular bishops are called to the General Council, they have a decisive vote, unless it is otherwise stated in the convocation. The theologians and experts of the sacred Canons who may be invited to the General Council have but a consultive vote.

81. Quae autem in memorata Nostra Constitutione Commissum Nobis de civili Veto seu Exclusiva, uti vocant, in electione Summi Pontificis ediximus et sanximus, hic omni ex parte atque integre renovantes, confirmata esse volumus. Quamobrem iterum in virtute sanctae obedientiae, sub interminatione divini iudicii et poena excommunicationis latae sententiae, omnes et singulos S. R. E. Cardinales, tam praesentes quam futuros, pariterque Secretarium S. Collegii Cardinalium aliosque omnes in Conclavi partem habentes, prohibemus ne, quovis praetextu, a quavis civili potestate munus recipiant Veto sive Exclusivam, etiam sub forma simplicis desiderii, proponendi. Ipsumve hoc Veto, qualibet ratione sibi cognitum, patefaciant sive universo Cardinalium Collegio simul congregato sive singulis purpuratis Patribus, sive scripto, sive ore, sive directo ac proxime, sive oblique ac per alios, sive ante Conclave sive ipso perdurante. Quam prohibitionem extendi volumus ad omnes interventus, intercessiones aliosque modos quoslibet, quibus laicae potestates cuiuslibet gradus et ordinis voluerint sese in Pontificis electione immiscere.

A disciplinary law which cannot reasonably be followed cannot bind. The legitimate electors by divine law can only consist of members of the clergy.  But who amongst the clergy can vote is a disciplinary law.  In the past it had been for a time the responsibility of the Roman clergy to elect the pope.  In an extraordinary situation they could do it again.  Keep in mind that the disciplinary laws concerning the papal elections were set by previous popes and were often ignored by the electors.  But those elections once confirmed not only by the electors but by the bishops of the Church were nevertheless legitimate.  The legitimacy of papal elections is something that has been treated by theologians prior to V2 and it is generally agreed that violations of the electoral rules do not invalidate an election that has been confirmed by the bishops.  But according to cuм Ex Apostolatus, heresy can invalidate an election even if the election was confirmed by the bishops.

85. Those who have been assigned to the Divine ministry by the first tonsure, are called clerics. They are not all of the same degree, there is a sacred hierarchy by which one is subordinate to the other. This hierarchy which is of Divine institution by reason of the sacred orders, consists of bishops, priests and ministers; by reason of jurisdiction it consists of the supreme pontificate and the subordinate episcopate. By institution of the Church other degrees have been added. (Canon 108.

So, Cantarella, doesn't that mean that we are waiting for these men to convert to the Catholic Religion? Or for some "pope" they elect converts to the Catholic Religion?  Doesn't that place the future of the Catholic Church in the hands of heretics?

I don't know...is it?  If these men who DON'T have the Faith can have "material succession" and can be "electors", why can't the Traditional clergy who DO have the Faith have material succession and be electors?  

I know there are many who think it is absolutely impossible for the Traditional clergy to be valid successors to the apostles, but as time marches on I wonder whether this is something that is just taken for granted in trad land.  

I don't have the answers, but I can not look to the Novus Ordo heretic-"bishops" for the next true pope.

Because some of them are already dead perhaps?

Regarding Papal elections, the authority remains in the Constitution Vacante Sede Apostolica, promulgated by Pius X, in 1904.  See # 17. "the right to elect the Roman Pontiff belongs solely and exclusively to the Cardinals of the Holy Roman Church". All others being absolutely excluded whatsoever ecclesiastical or lay position they may have.

Even if you wanted to argue as Clemens Maria said, that this Decree belongs to the realm of Disciplinary Law and could potentially be reversible, who could reverse it? Only a legitimate Pope has the authority necessary to abrogate a disciplinary Constitution of a previous Pope. In this case, Pius X, an unquestionable legitimate successor of St. Peter.

I know this is not what you or I want to hear, but it is what it is. Even conclavists must admit it, and they can become rather pathetic really fast (think Pope Michael). Reality does not go away just because we wish to. We, Catholic laywomen, personally don't need to be "waiting" for anything. What we need to do is saving our souls on a daily basis.
