Could the show realistically survive without TJ?

Bringing this up again after watching the reunion of season 40. TJ has been a staple on the challenge since 2005.…some of our favorite contestants are getting older and moving on? having their careers “revived” (to quote Jordan) or we get new players that inject something different into the game/dynamic. If TJ were to leave…would the show be the same? His part is small but the fact that he doesn’t overdo it is a core part of the dynamic…could someone ever replace him? If so, who could do it justice? I fear it would be devastating for the franchise if he left.
