If Inside Out has to go into Epcot, only WOL makes any damn sense. It could be done relatively easily, cheaply and quickly. And it probably wouldn't be considered a negative for many people. Would also restore some of the park's lost capacity. Assuming the pavilion is still in good enough condition to be usable. I haven't been in there for about a decade since they last used it for Festival space, so I can't say what sort of state it's in currently. But the main central space actually seemed to be in pretty good shape at the time.
Let Figment and Dreamfinder take back the Imagination pavilion and give it the proper money and care it deserves.
