Is it possible to use athletics for/with attack rolls?

I just started a game in 5e with a new human greatsword wielding fighter, and rolled stats pretty well [17 strength]. I chose the Brawny feat and basically gave myself expertise on athletics. Is there a way [feat, weapon, or magic item] to use athletics as either the attack roll or damage roll mod?

My DM is pretty cool with homebrew stuff, but likes to see similar existing stuff to help figure out balance. Are there any examples of skill checks affecting attack rolls?
