Something to remember: Nothing and Everything in 40k is canon. Female Space Marines seem to be completely out of the question, but a clever enough writer can fit them in. I've thought about doing just that. I have an idea for a radical inquisitor that is working to adapt the geneseed to Sororitas by using Repentia volunteers as test subjects. (lethal in almost every account)
Female marines are outside the pale, but so are Inquisitors. And their Acolytes.
You may of course do as you like but be ready for alot of critics to dislike the idea. Me included in that crowd. As for your heretical (because I think he's a heretic rather than a Radical) Inquisitor he won't have a pleasent day when he tries to use his experiments.
Your Inquisitor should burn slowly in the slowest Excruciator the Admech can devise!
