Might i suggest transfemmasc and/or adfemmasc but with transfaenine and transmaenine?
Transfamaenine/transfaemaenine in many forms (with some eyestrain I can't quite fix):
Adfamaenine/adfaemanine:
The muliberry purple color is my interpretation of that purple center stripe from the adgender flag, but shifted so it's distinct from the purple coming from the faenine flag. I tried adding it to the trans- flags for some variety.
