There's no such thing as an original idea. Just look at tvtropes. The whole idea is to make a new take on a previous idea, to integrate and innovate. No idea if this will be successful in doing that, but the premise alone shouldn't condemn it.
god this is like when everyone called first person shooters "doom clones", overwatch is absolutely not a tf2 ripoff lmao, and making a hero shooter does not mean it's an overwatch ripoff either.
