I would be down for a "Mouse Souls," but I do hope that combat gets better. Maybe at least a z-target or something. Definitely looks like a cool adventure game, but if combat is going to be big in it, it would need to be polished and improved. I hope that's what they intend to do.
Yooka-Laylee should be its own game with its own feeling. It shouldn't try to be like Banjo-Kazooie, it shouldn't try to be like Donkey Kong, it should be like Yooka-Laylee.
