bake the lora with 8 dim for as few steps as possible. intricate unique looking characters may struggle, though.
have multiple loras saved at different epochs/steps and use the early ones for base gen and swap to deep fry for hires. fix/img2img.
https://github.com/hako-mikan/sd-webui-lora-block-weight get this and start the lora a few steps in and stop the lora at about 50%.
you could also use the extension to try to find layers that affect the style without affecting the character that much (if such layers even exist).
