I think the bodies on the Pullip are fairly close to Blythe and probably wear very similar if not the same size clothing. Since I have kept mine in their default outfits (cause I got them because I liked them that way) I've never changed their clothing, but I've seen the nekkid bods LOL.
I think that you're doing an awesome project and I hope you document it here for us to watch!
