Remove them. All of them. Make them customizable. People have been asking it literally since dota 2 went into closed beta. It's pretty pathetically lazy that it still hasn't been fixed all these years later.

While you're at it add a legacy hud option since you guys rolled out a half-baked hud in its place.
