So this was done for a bounty and it mostly works in a sense. There's a little style impact because I had to train this one pretty hard to get it to work. Adetailer will probably be very useful. It probably won't work well if you won't prompt for a robot in some way.
Example Prompt: mecha_hair, robot_girl, mature_female, silver_skin, neon_lights, underlighting, sports_car, leaning, smug, holding_sword, katana, rain, street, lamppost
Notes:
Some hair styles will break the lora, most models seem to hate this concept quite a bit.
adding "wyre_hair" should help with generating braids in a robotic style.
After further testing, it doesn't work very well for established characters with mostly human features. It really doe seem like this is a hard concept.
Side note: I do take informal requests(basically a bounty that you don't have to pony up buzz for) if I like the idea(Tips are nice but not required since if it's a good idea then I'll get generation Buzz). Just leave a comment on one of my models or DM me. (Comments are preferred since that let's other people see that I'm actually fulfilling informal requests.) DMs are perfectly acceptable if your request is a bit out there and needs some image examples or something.
