To some extent it's possible to swap out the mitten and bar materials .

If you have trouble getting a specific style; Try rendering an image close to what you want then using it as a depth controllnet, with the lora strength and depth strength turned down to 0.6 or so.

Tried out renting a gpu for a full fine tune and lora extract on this one, think it turned out pretty good!
