Oh course that would be nice, but that simply takes way too long. It takes about a week to draw a character and there are way too many characters in the game.
True and seeing that you don't like the current art style of the characters in Lesbian Academy, I understand you want to change the design of every character but since as you said it would take long and is currently working on the next update of lesbian academy along with the nudist mode which will be released before or after for late summer probably June, July or august. Maybe you can redraw every character of the game after the next update is released, including Rainbow Dash.
