No idea how far you've got looking into this, but here's my thoughts.
Berry's Mix is a very good merge focusing on anime, you can find instructions on how to merge here. It includes using the leaked NovelAI model, which you may find you'll have excellent results with anyway, without merging. The other model you might do well with is Anything V3.0. These are both anime/cg style.
Character art may be the biggest issue. As far as I'm aware, to use AI to create character art and pose and stuff, you need to train it on your character, which you'd need to look into and have a system capable of doing so, as I have no experience on that.
And finally, as stated above, your system has to be able to run the software. I run it on a 1070, but I think it can run on on a 1660 too. It can be run on Google Colab though, so if you don't have a great system that's a decent plan.
