Unfortunately it isn't as easy as that. I mean it would make a difference, but I've just searched the code for places the IsMale field is used, and there's a lot of hard-coded dialogue too. E.g., There's no way of editing all of these out without decompiling the code, editing the code itself and recompiling it. You'd have to do it every SV update too. Here's a list of all the places IsMale is used (and ofc if IsMale is false, you're a female).
