Feedback/Suggestions for a new product idea (NSFW kinda?) (Patreon)

Hey patrons!

So I wanted to get some feedback on an idea. I noticed Vograce recently started offering Boobie mousepads as a product type. I kinda wanna design one, hahaha

The question is who to draw! 

Should it be an original character? Someone on twitter suggested Giri, my Oni girl. Or should I go with a popular fanart character? Something like Harley Quinn or Yamato or something.

This isn't a formal suggestion post for a poll, but I'd love to hear what you all think! Is there a character you wanna see me draw for this kind of product?

ps, update on the store; I'm counting leftover stock, going over what I wanna reorder, and deciding if I wanna make time for some quick new designs. A lot of newer stuff I'm gonna hold off for a summer sale, but hey, maybe I could make a mousepad design before I start ordering stuff.
