If it’s successful there, how about putting on a travelling road show. Our new bishop is vewwy vewwy qwiet about this so far, so a Franciscan nudge in the ribs might go a long way.
It was the Franciscans who spread the Roman-use of the Latin rite in the first place, before Pope St. Pius V made it universal after the Council of Trent. It would be completely appropriate for the various Franciscan communities to take part in spreading the "extraordinary use," though I would guess it's only going to be communities like Fr. maximilian mary's.
