I don’t know what level of complexity you’ve seen in your software buildouts, but at anything “enterprise” scale, building your own components from scratch is a recipe for absolute disaster. There are so many nuances, especially with accessibility, and edge case bugs, that I would really strongly recommend against it. And by extension, I’d be against this approach.

Maybe you could make it work if everyone agrees on a base set of headless components to use, but we seem to be moving in the opposite direction with things like ShadCN.
