That problem went away in the end as the client changed direction. My big issue with it was having a separate texture for each leg as the files were real world print size and I couldn't have made a single map big enough to hold them all. Had I gone ahead I was thinking about projection painting some marks on each leg for say 100cm, which would have allowed me to just render out a slab of texture and then measure it up in pshop. Or on a similar note to test run it with a chequer shader over my main texture.
It was a weird one, as rather than putting texture on model I was rendering a big flat slab of texture and then re applying that to the model for visuals, originally texture wasn't required to be on model but only printed, and finally just a big 4m slab of texture was what was supplied.
Im still a bit confused over the need for everything to be square and need to look into the BP interface a bit more, if I have a pack sleeve or something at say 40*20cm and i bring that in as a texture, I end up with my UVs jumping from square to stretched etc, but using a square just adds lots of wasted space.
Another thing on the study list.
