A universal indult for the Tridentine Mass could be part of that reform. However, a reform of the reform recognizes the legitimacy of Vatican II and of the Novus Ordo and therefore the suppression of the Novus Ordo and its replacement by the Tridentine Mass could never be a part of it. Hence, although many traditonalists could be part of this reform of the reform, the extremist traditionalists could never be part of it since they think that the Novus Ordo is fundamentally flawed and beyond fixing, that it cannot be reformed.
I agree with THIS statement totally. Many decry the hurried nature of the translations of the Mass after Vatican II. I lived through the entire thing so I know all too well how things went "higgledy piggledy" and many good souls left in confusion.
I think we are now in a phase in which WHAT the Council said will now be implemented on a gradual basis--a phase of consolidation and some reversal. That might include saying more of the Mass in Latin in the N.O. Mass (as was done on EWTN) and more faithful translations of the parts in the vernacular (we are seeing this now).
The garage sale nature by which statues were discarded, altar rails ripped up, votive candle stands moved out of the Church and the Tabernacle almost hidden will gradually be reversed. In all, I believe the discussion will be to reassert "vertical worship." The horizontal worship centering on the Assembly is not Catholic and has led to some horrible liturgical abuses. Listen to Fr. John Corapi if you want more amplification. The priest is acting in "persona Christi" and is neither a moderator nor a presider. His role is as an "alter Christus."
