Im not sure I understand your question.... but if its can you use the V3 & A3 hose textures in the material room on Miki, the answer is no, because the UV templats are completely different. You could try downloading a hose, overlay here (in freestuff) meant for V3, and just adapt it to use over your existing Miki texture in photoshop.
