I decided to run your mod with Chex Quest 3, and it works quite smoothly! The only problems I found was that the names of all the Chex objects were their source-code names, and that most of the Mr. Friendly-unqiue assets assumed you were running the Doom Series, so if you do plan on adding Chex Quest 3 support, you don't really have to worry about much gameplay-wise [maybe aside from the immobile 'boss' that spawns at the end of Chapter 1].
