Nothing is wrong with Mode Switching, it's totally valid. I just think we don't need a power that is that similar to Mode Switching as A-S Mode would be.

High Speed Deformation just sounds like Elasticisty, and for your example you brought up the anime poster boy of Elasticity. If it's just "You can bend fast than one would think they could", that just sounds like Enh Dexterity/Agility (depending on exact application).
Alternate Self Mode and Uneven Movement are both obscure, and need a KU. I thin it'd be best if you could only ask me to eyeball powers that you have a KU in mind for since that's part of the minimum bar for entry for a power anyways. Not that I mind discussing powers - it's why I'm part of this community after all - but just because it'll help to clarify what a power does and check that box so we don't spend time analyzing a power only to find that it does not exist in fiction.
