Mario Kart Live has me curious if Nintendo would be more open to outsource bigger franchises like Mario Kart more often in the future. At least giving them the benefit of being co-developers.
Velan Studios is made of ex-Vicarious Visions guys, and I'm already noticing lots of unique animations on Mario/Luigi that we wouldn't see in a more rigid template of animations from mainline Mario Kart games.
Smash certainly would benefit of fully going Bamco only next time, if Sakurai feels like retiring from the series. Heck, I'd say a 3rd DLC season for Ultimate solely made by Bamco guys would make a good test, with Sakurai just as supervisor of sorts.
