Highlight Face Orientation on Selected Faces

I know, there are some similar suggestions regarding face orientation highlight. But I didn't find what I'm looking for.

I don't want to have the face orientation highlight on all the time but for me it would be super helpful to see it when I select faces of a model in edit mode. It would prevent a lot of mistakes that aren't visible until they make problems.

My suggestion: Just make the color of selected faces slightly different depending on their face orientation.

Here is a little mockup. Could be even less obvious.
