I don't think that's what he meant - he's not saying make an infringing game, ask for permission, then distribute anyway when they say no. He's saying to make a non-infringing game, but then asking if he can have permission to use things like characters. If not, there's no infringement with the original game.
HORRIBLE IDEA.If they don't, then you just release your clone anyways.
Developing a game with a placeholder asset that you don't intent to release, or for the purpose of pitching it to a company, that is one thing.
But what you just described is willful infringement.
I'd agree it's a bad idea to do it anyway; they'd still likely say no. And it probably doesn't help to go telling another company that your took your ideas from them, even if it's not something covered by copyright.
