That depends.Is there anyway we can petition for them not to do this? Moana doesn't belong in Epcot at all. Maybe we should say we are offended in someway. That seems like the new way of getting rid of something.
"My great great grandfather drowned in water. ... Well it was either that or the fall... into the well."
Moana was a story of the importance of nature and supporting and protecting it. It also focused on how life is tied to the water.
If they use some education aspect to tie to Moana IP, it could fit.
I get the negativity of IP into Epcot, but unfortunately that ship has sailed ever since they put Frozen in Norway and the Three Caballeros in Mexico, heck Figment in Imagination.
So, if it has to be IP related, if it also ties some to education...it could work.
