It's still a stupid idea. Canonical crossovers absolutely shred the metaphysics and pataphysics of both settings, both from an in-universe prespective and a writing perspective, unless the universe is specifically set up to handle them, via parallel universes or similar, with sufficient tech, magic, or their underlying rudiments on both sides to account. Or one or the other is small enough in scope scales that both could plausibly happen in the same world.

Nor has any reason been given to suggest that the most appropriate cross would be this universe with what looks like an absurd and demented one which makes no sense to an outside observer. A case has not been made.
