Definitely, though I can understand if they want to keep it exclusively for costumes you have to purchase for the added value. (Or course I'd love it if all outfits had the functionality.)
Really though, it's time Capcom starts being more even handed with the sexy alts. I get why they pushed the female swimsuits first, straight guys love boobs, and they make up the bulk of the player base. But after the overwhelmingly positive response to Hot Ryu, loincloth Urien, and now this shirtless Necalli variant, it's obvious a lot players want the beefcake too. Whip up some swimsuits, give them some kinky variations like the ladies got for their bikinis. It's money that's just sitting on the table.
P.S. Hurray for an Alex player winning a major tourney. More Alex support please.
