I might just do something like that. Although I inevitably get caught up in designing some minor tech part.
Last time I attempted something like that I made stack machine texture maker, then embedded it inside a version of TTT that minifies+gzips to under 1500bytes. After a few years of pondering I think there are a few more enhancements to be had.
For reference, This URL has a bunch of textures in it.
