An IP can base itself around a great concept, but if executed poorly is worth fuck-all. See: No Man's Sky, and why I'm glad I didn't pre-purchase. Love the concept, but the experience as-is is too shallow.
You'd have to give me compelling reasons to accept your random animal beasts as an alternative to the vast selection of Pokémon I've come to love.
