It's a bit time consuming. Doing one char took me 30-60 minutes with the doing the mod, testing, ect. Doing 10 extra chars would just be a bit time consuming. I'd either need to do it all by hand or develop some tools to speed it up.
Tell you what, you find me some data that identifies the mod files for various in game customizations (like what mod files represent X hair or Y top?) and I'll spend some time and make that mod for you.
