It probably _could_ be, but I'd probably have to build (or hire someone to build) some sort of external app / database to manage all that.

A simpler solution I thought about what recreating the layout in Figma or Sketch, then someone could create their own palette simply by tweaking color swatches (and have it auto update on the mockup).

It might be easier to get someone to build you a bookmarklet that uses JS and puts an input on the page.

Do the tools you're using (webflow) not let you put any custom JavaScript on the page?
