I'm in the Resistance today (a.k.a. "Old School SSPX") because the SSPX priests I knew did precisely what you suggest. But unfortunately, they are rare, unappreciated when they do their jobs thus, and many are sent to the Missions in third world countries to please the lukewarm "trads" in the American chapels who were complaining.
And unfortunately, that group is growing larger all the time. Sanctity in the SSPX is becoming rarer, and requiring more and more PERSONAL individualism and initiative to achieve. In other words, it's not thanks to the priest -- just the person and God (with perhaps some heavenly intercessors in the mix).
Remember, there were holy people who knew and lived the Faith in the Novus Ordo too -- thanks to buying and reading TAN books in their personal time. It wasn't thanks to their Novus Ordo parish or the priest there. If they become holy, it was IN SPITE OF their parish, IN SPITE OF Vatican II, not because of it.
The same is becoming true of the SSPX.
