An idea I just thought of. I like how they are emphasizing the "United States" in the United States Title, and I also like how they have image plate changes for the WWE World Heavyweight Championship.
Two midcard titles are silly. A cool idea would be to unify them and turn them into some new, "National Title" or something like that where the winner has the center plate of the title changed to an image of wherever they are from. Plates for the U.S., Mexico, Russia, U.K., etc. Would make it a lot more interesting and meaningful imo.
