The only three names that IMO would be somewhat interesting would be Bobby Lashley, Matt Riddle and Damien Priest. I could see AJ Styles winning it to pad his resume as well.
If they were smart (
) they'd have Bron Breakker enter the Royal Rumble and have a great showing before being eliminated. He's too green right now, but he's probably going to be at the top of the card by Mania in 2023.
