Imo the ending should be (or planned to be) bringing everyone together and not hiding it from the others (currently they don't exactly hide it, but if I understand the scenes correctly they aren't open about it), which have 1 very big problem.
All the different routes for every character, so you would need scenes for that with in character reactions depending on the route for every character with every variation.
Ofc there is the option that I think everyone (or most) would be okay with to just have the current scenes finished (have some extras maybe), then tie everything in with one ending scene, which would have these variations. So no group scenes besides maybe the ending.
Also somethingneeds to be done about the ghosts too.
Unless he plans something completely unseen, like all the characters got posessed and that's why they weredoing these things, so breaking that would just make all the shenanigans stop, that would be a very strange ending though.
