i second that - a remapped posette would be much better.
the problem with texture converters is that they seriously deform/stretch/blur any texture. so right away anything with tattoos, markings, freckles, etc is out. they are good for a quick conversion for a middle-distance character, but for any closeup work they are highly noticeable.

there were some very good textures available for posette in freestuff, buy staale, snowsultan, etc. why not just use one of those?
