Unless they can make them circumstantial (e.g only on Risa, your ship interior, etc.), I don't see this happening because I'm pretty sure CBS (rights-holders on the Star Trek property) and by extension Cryptic (who has to run things by CBS) don't want an ESD full of half-naked toons doing jumping jacks or pantomiming lewd acts.
"But KDF gets scantily-clad Orions!" you rebut. Yes, but that has basis in canon. Outside of a few "fan service" episodes, swimwear was rarely seen in the shows.
That said, I would love to have the option ("speedos"/trunks are unlikely but maybe those board shorts the guys are wearing on Risa, and some barefoot or sandal options).
