My only real concern is just how big she can get. I'm not sure that someone who can grow to the size of a kaiju really fits with this setting. Might I suggest limiting her growth more to the levels of say, Giant Man or Giganta.

Alright, I can do that. Around which  ballpark would you think fits for a decent and yet formidable maximum size?
