I really doubt it tbh. Not only has never needed to do the job, he clearly never really thought that much of it.

with the pandemic now putting a block on live shows with audiences until at least sometime next year (maybe longer), it might just be enough for brock to get out of the cycle and get interested in something else, and therefore have no interest in returning.

Specially now brock is 43, I can't honestly see the guy wrestling for much longer regardless.

However, I wouldn't be surprised if vince offered enough for him to return. It seems fairly logical that vince will want some big stars back when they can start having audiences again.
