It took some doing, but I've started rewriting the TF start files a bit.
Basically the current TF start is unsatisfying, I think. You build a character, then immediately change to a different character. There's no sense of change within the game, because you don't even get to start playing before it happens.
So the rewrite disables the forced change, and substitutes one of two (or both if enabled) alternative methods that key off of player actions. This means you can play as your first character as long as you like, then either by accident or on purpose, transform into a different character. The narrative is adjusted to remove referencing a timeframe, so it's not jarring no matter how quickly or how long you choose to linger before changing.
Also starting to adjust some of the events to make them less prone to assuming the TF is 'MtF' and be more broadly applicable. There are events that clearly only apply that way of course, and in those cases it might be interesting to add alternative versions that work the other way as well.
It's a bit of a rabbit hole though! Lots of permutations to think about, and the scene/action system is not easy to use, hehe.
Still, I can see the appeal of 'modding' in the system. With a bit of expertise, it would be possible to create all kinds of scenarios. With a bit of patience and diligence they could even be fairly complex.
It'd be cool to see that reflected more in the releases.
