It does indeed appear that to err on the side of silence-- e.g. not offering tweaked poses, unless the original artists are keen to have you do it-- is the wisest course. But would a tutorial on tweaking be out of place? Surely the community at large that still doesn't have Victoria and Michael (not naming names... erm... mea culpa) would benefit from the experience of one well accustomed to helping poses translate from one model to another? If it's feasible, that is.
