I think that there are several things to consider here.
As someone said, the Church is not asking our opinion on the matter. At this venture, what the rest of us want is irrelevant to the Cardinal Levada, who is the one who will be making the final recommendation to the Holy Father. Cardinal Levada is not one who can be intimdated with the threat that “we’ll leave”. He wants unity, but he does not yield to that kind of pressure. He is very faithful to the Holy Father. He will demand whatever the Holy Father wants.
When a reconciliation does come, there will be a shism. There are certain SSPX priests and at least one bishop who will not submit until they have converted Rome. That’s like painting yourself into a corner. Everyone has to be willing to come part of the way.
The restoration of canonical status is going to come with conditions. The bishops of the SSPX will either be isolated in some structure just for the SSPX unless they agree to join their brother bishops in the mainstream.
I agree that the SSPX can do a great deal of good, but they will have to make some sacrifices.
We have to pray that this and other things that may go down, will happen smoothly and with great charity.
