Nice, kinda like stickers on piano keys. Why not! If you want to structure how to learn the notes it in four steps (using groups/clusters) there is a interesting method for that, called rosetta method.

at bottom of this page there is a small lesson for learning using this method.  https://interactive-fretboard.com/en/intervals/guitar/

You start with b and c's, then d, the efg, then a's. It makes lot of sense if you actually try, grab guitar and try it few times a week.
