Body-changing adeptry?

What official or fan-created adept schools out there that are capable of changing adept's body? I mean, epideromancy, duh, but (a) a trans epideromancer has been rather famously already done in the setting and (b) it's too stereotypical and touches too much on images of us I'd like to not casually perpetuate

Context: I'm working on a character for an upcoming streamed Unknown Armies campaign, and it's rather important that she be both trans and pregnant (an inversion of Odin ~ instead of a sacrifice of herself to herself, she is pregnant with herself from herself). I kind of want her to have an adept school to justify this magick, tho there are plenty of ways to explain it without that (rituals, items, other people being adepts, etc.) but I'ven't yet found a school that felt satisfactory.....
