If you're good in Photoshop, it's simple enough to rebuild a P4 texture to fit a P3 figure. I've done that several times, and the results are always remarkable when you think what a P3 looks like. Check my gallery for Backstage 13, and you'll see what happened when Lawboy got moved into the new century. Very different from the original model, and all it took was a new skin texture and a new hair prop.
