In the current meta if you want any kind of competitive viabillty you need to be a human or blackleg for the geppo because theres no race/fighting style that can even compare to the amount of mobility geppo gives (exept from fruits) so its almost a necessity to choose human or blackleg.
Some possible solutions include
Directional electric missile for mink (aka allowing to be aimed up or down)
Cyborg Coup de Bou made similar to mera's heat dash but weaker
Very small speed and jump height increase with Doriki gain
A strong leap move for brawler.
