Hi, I’ll tell you what I would do and maybe that will shed some light.
I tend to never use stroke unless I need some taper (then I go for 3d stroke), so I would copy every single path and paste to a shape layer. This way I’d have a built in wiggle through the wiggle paths modifier.
After setting that up, I’d create a new comp with a hard clipped animated B&W noise/texture, with just a little bit of gray. I’d use that as a matte to roughen my edges a bit and create some lightning effect.
