I just wanted to resurrect this topic to say that I keep finding my mind wandering back to the joke about "Big Trans" sounding like a superhero name and Amelia Blank's subsequent fan art of said hero, just because I feel like the idea of a trans lady who can change size at will ala Ant Man fighting crime and righting wrongs to actually be a really rad idea.
I think she should be a really quiet and reserved lady in her civilian life, but then when she's in super mode she's all bombastic and over-dramatic ("Larger-than-Life", you might say)
