Didn’t know they had ever done any Fox titles.
It all depends on how much Disney/Lucasfilm cares about the OOT. If they don’t see a niche label release competing with their own SE trilogy releases, they might be okay with it. There were standard Laserdiscs and DVD’s of Armageddon and The Rock concurrent with the Criterion releases.
Criterion doesn’t really advertise beyond it’s devoted fanbase, and you don’t see their titles for sale at Walmart.
A downside I can think of, if it ever came to that, is we would have to kiss any chance of seeing the theatrical prequels goodbye.
