What about Mike/Zoey or Sam/Dakota?

I doubt they'd bring Mike back after generating controversy in TDAS, which could bring Zoey down with him, however the writers seem to like them, so they're a Maybe in my opinion. Sam and Dakota on the other hand I think is VERY likely, considering Brian Froud (Sam's voice actor) posted a now deleted tweet about the Ridonculous Race, indicating Sam, Harold, or a new character voiced by him will be competing.
