Late reply, laptop was getting repaired. For sfw, i built my own tool (not publicly available) and connected that to API's for nano banana pro, seedance, etc as needed. I have pre-set up modes and settings how i need it which is handy. You can just use 1-2 reference images of your creator (a full body pic + face pic, or a full reference sheet if you want). Nano banana pro is elite when prompted correctly
As for nsfw, i have trained a LoRa which can be plugged into a workflow for her character, still fine tuning a few nsfw details though. I haven't experimented with any of those sites but i know a few you are refering too, they seem decent, im not sure how consistent their identities will be.
