Multi character WAN Lora training?

Greetings. I have successfully trained several WAN loras for single realistic characters, (not real people) that are very high quality and nail the likeness. For context I have an RTX 5080 and train usually at Rank 96 on AI Toolkit which takes me roughly 50 seconds a step to train. If I knock it down to Rank 64 it trains around 9 seconds. I test at the lower rank before bumping up to 96 for the better quality. My issue is because I don't want to mess with masking and inpainting workflows that have limited success anyway, I want to train several characters in a single Lora.
