Pretty sure I can just counterpick Sanic there, particularly with some of my custom moves.
As a side note - I'd also like to recommend Mute City as a counterpick stage. It doesn't have a main platform exactly and the floor bounces you, but the hazards are warned well in advance with the CHECK indicator and the platform movement is pretty lazy. Pac-Maze to a lesser extent, the ghosts tend to stay at the edges and there's pretty significant risk involved in going for the power pellets. For the stages mentioned in OP, I think both are pretty good counterpick candidates, Tomodachi slightly less so.
