Nosepass Low? Probopass might have a niche in being a steel-type that can defend specially. his typing is bad but he can rid one of his x4 weakness with magnet rise, he has sturdy, and Steel is just an overall useful typing ingame, and Lock-on + Zap Cannon nuking endgame may be useful (although it's better to just twave outright). Mid imo, although he's really just hanging around there.
Buneary might be ok because you can use 102 BP STAB frustration immediately, but the big problem is the evolution which is very painful because of Buneary's 0 base happiness. The instant utility might be good for low, but idk
Most of these are fine imo (although i'd push Druddigon to bottom but the reasons don't really hold). I'd argue for Zangoose too if it didn't just so happen that SD is now L43 instead of L9. That's just dumb. >.>
