Just get one avatar and maker a version of her flat and modify another verison to be big booba 
I'd say koyuki/kokoa work well for that. just set the big booba to 150 or 200 and you're there. just might need to adjust some clothes a bit.
Wolferia can also work, but i have never done a flat wolferia, only booba. have fun with unity, anon! hope to catch your cutting boards and bandonkahoonkers in a meetup one!
