This was basically the solution I proposed earlier in the thread- yes it could technically be considered heresy and could trigger a purge, torture, the like. But if the local watch commander/inquisitor/what have you decided that the female 'marine' was of use/a potent tool, was worth investigating more closely, etc. it's not out of the question that they would be allowed to stick around.
Yeah, the "Empire" would burn her to death, but not all inquisitors, and not all watch captains think the same way. There are fluff examples of, at least inquisitors, that work with people, creatures, etc. that would be considered heretical by the 'larger organization.' Wasn't Ravenor the one who worked with the Eldar, more than once, and kept it a secret from his own Ordo? The needs of the many and all that...
The fluff way around it is to create an environment where it could exist, and treat it as an rarity or a potential 'if you talk to anyone about this we will all be purged' kind of way. Hell, the inquisitor/commander doens't even have to tell the PCs why they're doing it, just that they're under orders and it comes from on high. You could have a field day with all the RP opportunities such an event could have- think of the inner group conflict, what if one of the group decided to try and report home as to what was happening? Does the Kill team become a rogue element? There are ways to do this without completely obliterating canon that could create really engaging stories. Does it go against the grain, yeah, but sometimes that type of conflict is what breeds the most exciting stories.
@Gantz: Why couldn't it be from his genetic material? There are a only a handful of things at a genetic level that keep men and women different (you could say the same about monkies, too), so why not take the stuff that doesn't involve the dude parts and stuff them in a lady? I'm no geneticist, mind you. As for your second question, I'm afraid I don't understand what you're saying - if it's why did the Emperor give only women the ability to procreate, he didn't, humans just came that way. If it's why he didn't turn women into SMs, your guess is as good as anyone elses'. If you're saying women, because they can bear children, are the most valueable asset the empire has, then I agree to a certain extent, but when you have billions of people, and half of them are women, having a few of them march to their death won't actually endanger your species.
