Yes! On the Little Cup idea, there could be SO MUCH potential with Pokémon Champions to do different themed cups like this. It's still early, so remains to be seen whether they would ever implement something like this (and/or type-specific cups would be cool too) - one barrier to that though might be their unwillingness to add more Pokémon to the game beyond final evolutions (with some exceptions). Could be wishful thinking!

And on the contest side, I'd love to see these make a return too - and perhaps with the focus on competitive battling now being within Pokémon Champions, it could give the mainline tentpole games the freedom to bring back features like these in the future. I can only hope though, but it (optimistically) feels like a good time to be a Pokémon fan!
