I'd buy - a complete package for me would include a remap of the V4 to V3 figure as well. When V3 was released, there was a remapped version which took V1/V2 textures, available at DAZ - Will Dupre mentions it in the DAZ thread that's linked above. It was distributed as a UVS file which could be decoded using UVMapper IIRC. I'd hope that DAZ's attitude would be the same; if it helps sell more V4s, then it's fine. ;)
