I don't do "genderbends", no, but I do have a trans AU for my main character, Edwin.
She's fun, because Edwin has always been very gender nonconforming, though obviously leaning masculine in his presentation. Adjusting his design into something more feminine, while still visible as the same character only required a bit of makeup and hair change, along side some nice changes from HRT, of course! The intention is mostly to highlight that Edwin's character design can easily be read as "female" with little change.
It's also not a coincidence that she shares more of a resemblance to Edwin's 80s attire. The introduction of lipstick on Edwin is what gave me the idea in the first place!
I never decided on a transition timeline for her, since she is mostly a fun thought experiment rather than a fully realized character. She's basically the same as Edwin, the only main change is that she is openly bisexual, instead of Edwin's perpetual closetry. When you're already openly queer in one way (being a trans woman), the idea of wanting to hide your sexuality as well seems, well, pointless. Otherwise, she's just as cunning, ruthless, and egotistical as her cis counterpart.
