They can very quickly switch it over to a Roger Rabbit overlay if they'd just hang signs on all the characters identifying them by their new names.I think the best chance for something like that to occur is if there's a slow recovery from Covid and the company finds itself in a difficult financial situation. In that case, I can imagine there being some internal questioning about whether spending large sums of money to refurbish one of their most popular rides at DL and WDW is really so urgent a priority.
I still think it will likely happen. Honestly, though, if this hasn't happened in 2 or 3 years time do you think anyone outside of the fan forums will still be talking about it?
