Generally they tend to mostly go after games starring their characters, and usually leave other types of fan works alone. They also don't go after all fan games either, with 99% of them being left alone and close to 100% of ROM hacks being in the same boat. It's also mostly remakes/games rather similar to remakes or official games that get targeted in most cases too.

So no, I don't think this is going to provoke a cease and desist. It's not competing with anything official, and barely even counts as a fan work at all.
