It could happen. If it does ever come back, I don't see it happening Roman rite-wide. Maybe certain countries who have a shortage of priests consider it.
It would also be the only way a married Pope would ever exist, as cardinals (at least in these current times; there have been cardinal-priests and cardinal-deacons, even) are derived from the episcopacy and in the East, they come from the monastic orders and are celibate.
