Ohh i know i can get female guardsmen (and better looking) from other places but i don't think i would be allowed near anything GW related if all my miniatures is of a different brand. XD
I also know how to make Cadians females (slice and file) and since i want to avoid any ridiculous boob armour i can still use the regular torsos. Like those Victorian models you mentioned.
A pain in the butt, sure but i am talking about starting with max 10 female figures and max 25-30. Not to much work i say.
You think that fluff wise the merks should be considered better equipped than let's say pdf? You might have a point, maybe clean them up a little then.
