XV2 Cel-Shader Progress Update

So for the past couple days I've been trying to come up with new methods for getting a cel-shading look that was more consistent than my previous versions (Type1 and Type2).
I thought that by having completely decompiled and reversed the character shaders I would have an easier time (and it has helped a lot!) coming up with ideas that could work better.
testing was promising at first as shown in the Omega Shenron image, but it completely falls apart with transformed characters as shown with the Majin Vegeta image.
I think I might have been trying to think too hard with how to do things and what I should do instead is go back and look at how I did things in the first versions of the Cel-Shaders.
I got a bit too caught up in the excitement of what I could do now that I had actual readable code that I wanted to try something completely new instead of just doing what has already worked and what people seem to like most.
I wanted to have a WIP version out tonight, but since this idea doesn't seem like it'll pan out at all, I'll instead have to try again in the next day or so.
