I think that would be the most meritorious path. Patience makes saints. The SSPX was founded on impatience. As St. Robert Bellarmine said: "True patience enables us to bear the misfortune of suffering without incurring the misfortune of sin."
Or, as St. Catherine of Siena says, "Consider that the love of divine charity is so closely joined in the soul with perfect patience, that neither can leave the soul without the other."
and in another place:
"The sign that you have this virtue [of obedience] is patience, and impatience the sign that you have it not, and you will find that this is indeed so, when I speak to you further concerning this virtue...When He returned to Me, rising to Heaven from the conversation of men at the Ascension, He left you this sweet key of obedience; for as you know He left His vicar, the Christ, on earth, whom you are all obliged to obey until death, and whoever is outside His obedience is in a state of damnation, as I have already told you in another place." (and this was a time when the papacy was a mess in general).
Archbishop Lefebrve was commanded to ordain only one bishop--this is not contrary to divine law--and yet he was impatient and so he sinned. He was scared that he would die and the faith would be lost with out additional bishops. He forgot about the will of God and that it is Christ who is the head of the Church. In his haste he forgot that when we act through the lawful channels God will make sure the right end will work its way out--even if this may take time (requiring additional patience). If Archbishop Lefebrve would have acted with more patience and mildness, showing forth the fire of charity--because as St. Pius X said, "charity wearies not with waiting"--things would be in a better state than they are now. There would be fewer excuses to fear traditional movements and the old missal, it wouldn't have the baggage it has now. The bitterness has done more harm than good. It has hardened hearts to the cause, rather than softening them.
Sts. Athanasius and Basil were even persecuted by the Church, but they gave the evil hiearchy and indifferent Pope (at least in the case of Basil) no reason to place them in a negative light--Athanasius was unjustly excommunicated, but he never committed any acts that merited that penalty. They bore the persecution patiently, and things worked out as the orthodox believers supplanted the heretical, as new Popes rose to the chair, and as the Holy Spirit did His work.
A different, but no less important story, is that of St. Hippolytus. He was in a similar situation as Archbishop Lefebrve. He was one of the top theologians and bishops of his time--a great success in spreading the faith and defending it. St. Hippolytus also fell into a similar trap. He was dismayed that the Pope (St. Callixtus) was not taking any action against heretics--and in fact seemed to be favoring them. Feeling his way was better, the way he knew was more traditional, he went out and did things on his own. He attracted a great many followers too who are also dismayed with the state of the Roman Church. Glory to God, he repented of that decision and reconciled with Pope St. Pontianus in the salt mines (they were both persecuted by the Romans) and wrote to his followers to reconcile as well. He died a martyr and is counted among the Saints. This fork in the path is still available for those who are on a similar path that St. Hippolytus was on. It takes such incredible humility and patience, that it is surely to be almost supremely sanctifying.
