It sounds wise

Pope Said to Weigh Takeover of Scandal-Plagued Legion of Christ

"Catholic Church Investigating Powerful Order Wracked by Pedophilia Charges Against Founder Father Maciel"

I think that the Legion would likely accept a 'commissioner'. They seem, despite their old extreme dependence on (and almost veneration of) their former leader, to lean toward supporting the Magesterium of the Church and so would most likely accept the decision of the Pope. It's not likely that the Pope would require them to change their focus and spirituality radically.
