(Help needed/appreciated) Creating Maruki from the BBTAG chibi models

[steel kite]

Hey guys! Recently I saw those adorable Kotone and Makoto/Minato chibis edited from the Blazblue Cross Tag Battle game. I've always found the lobby chibis to be cute and I want to see if I can try to make Maruki using Hyde as a base (for the most part). However...I need a little help. I know how to recolor textures and how to do very edits but at some point I'll hit a road bump. Specifically? His hair, pants, and shoes. I have no other worldly clue how to edit the texture so it will work with his hair, as each character has their own unique hair style. And I don't know how to add something ONTO the texture vs remove or recolor. I'd also love to have him rigged, but I'm not getting my hopes up. I'm willing to fork over some money if somebody is interested in helping but wants some pay. So far I've simplified his hair down to work as a chibi + his glasses.

Not 100% satisfied with his tie, but his tie and shirt are done
although the lighting makes it hard to tell that his shirt is blue now

Tie, shirt, skin tone for arms and two of his faces changed, eye color of two his expressions changed. Still have to figure out how his jacket works... that weird belt around the jacket is tricky to edit. I tried replacing it with another color, only for it to go through part of the tie. Gotta tread carefully. Certain expressions like this one will be altered. I plan to try and rotate his eyes a bit so they're a little down turned, as well as rotate his eyebrows to a more neutral angle so he isn't looking so angy
unfortunately the lighting is kinda killing how the progress looks
That weird light patch directly below his head doesn't appear to be a texture error; there's virtually zero neck with a small gap between the head and shoulders. I'll have to try and fill that gap

I managed to change his first expression so he didn't look so angy
unfortunately the mouth is a bit offset and I haven't figured out how to fix it....

Did a huge change in expressions compared to his regular textures and matched the rest of his faces skin and eye color
not 100% sure how to tackle his coat...i'll think about that tomorrow
