Variance in artist styles across checkpoints

I've been messing around with combining and weighting artist styles (anime) in Illustrious to create a unique look, although with little success. Ironically, I've found that the combo looks fantastic on NovelAI 4.5 but I don't want to subscribe for that. NTRMix isn't cutting it and WAI is better, but still far from how it turns out in NAI. Does anyone have any good recommendations for models that might process those style combos closer to NAI? Or should I just keep doing trial and error to get it to work in the models I already use?
