Tested out using an XL model for main gen and then a 1.5 model for upscale with a character lora to try and get some of the character details that XL didn't know without having an actual XL lora. It clearly helped somewhat but it's not great. Wouldn't really recommend it as a technique, I was mostly just curious what would happen
