No, textures are model specific. If it is a P4 texture it will only fit P4 characters and if it is for Vicky, then only for Vicky and Vicky characters. However, you can adapt a Vicky texture for P4 or vice versa. I have done it with several of Anton's photorealistic textures (found at Propsguild, I believe) and one of dthuregrif's--adapted for Vicky. You need to have an understanding of how to create a texture and also how to use a graphics program with layers, but once you do, you can 'adapt'--but never use directly one for the other.
