heyas; textures: the figures are mapped differently. some people have tossed about the idea of remapping this or that character to take other maps, but i don't think it's been done yet. (except in one package you can buy, but i dont recall which.) hair: yes, you can interchange hair on any/all figures with some repositioning and scaling. props: same as hair. clothing: you can't conform clothes made for one figure onto a different figure. you can work with it and make it fit, but it may not pose right. you can do even more work and translate it into a conformable bit that fits on another figure. but out of the box? no, they're incompatible.
