Possible to have buttons in Mask?

I’m toying with an idea for a navigation bar/menu. I want to have the bar appear on screen with just one letter for each section (H for home, N for news etc) and have a slider that when moved over the letter reveals what is masked underneath (slider over H reveals the word Home) but then have the word be a button so it can be clicked to go to the Home section.

Does that make sense and would it work or am I not being clear enough or it just won’t work with a button in a mask??

Thought, ideas, comments.
