Does Adventures of Lolo count?
Take this:
Make it look like the Link's Awakening remake or something like that, add a level editor so you can share levels Mario Maker-style and it's golden. Doesn't even need to be a retail release, I'd be fine with an eShop-only game. Maybe put Kirby as a playable character or even disguise it as a Kirby spin-off even, so it gets more attention.
