I'd rather not, the closest we've ever seen to this I think is the Moonfire Faire from last year having the one young Miqo girl in a swimsuit. You can try to argue lalas but realistically they are just dwarves(Even more so with the First being a thing). Adults that have small bodies so you'll be judged but they wouldn't already have those risque outfits in the game for them otherwise.

Rather not have the best MMO on the market be plagued with "It's great for lolicon/shotacon immersion" as a selling point if they were going to attempt this.
