I haven't ever considered it for trans guy Doms, hm... I have a couple transfem Dommes friends who are really into self-directed detrans kink in a cathartic "I guess if everyone thinks of me as a secretly evil man I might as well be" kinda way and like to act as misogynistic dykebreaking predators and the like during scenes. Basically, sexualizing the typical anti-transfem TERF brainworms used to hurt them to take power away from them.

I guess a trans guy dom version of this could either be "turning into a husky dommy mommy" to help a female partner "accept her lesbianism", or "fixing" a gay male partner's sexuality and telling him he's just imagining things and is secretly straight. 2 different flavors of orientation play!
