Was getting a bit weary of all the unwrapping so I thought i'd make 4 small textures and this was the result.  still a problem with the white outline on some parts but that can be sorted.

**EDIT - managed to get rid of most of the white outlines.  it's barely noticable now.  I also halved the texture size and it still looks good.  they're all 128 now.  I think that should add enough variety but I can always add another colour if it starts getting monotonous.  new pic below: what do you think?
