Who should be the main event big man of AEW?

For AEW's main guys like MJF, Page, Ospreay, Swerve, Moxley, Omega, Copeland. there's no classic big man. Let's say AEW decided they wanted one to give them different types of match storylines and appeal to people who like big guys. Should they make it one of the guys who've done it like Joe or Lashley or try to push someone like Hobbs or Bill?
