#2. Make him the special guest referee at Stomping Grounds

Baron Corbin, for some reason, is allowed to have a special guest referee of his choosing for the Universal Championship match at WWE Stomping Grounds 2019. Sami Zayn is the most obvious pick, especially since he directly offered to fill the role and even had a "trial" run on the last episode of RAW.
However, WWE could decide to take us for a rather pleasant swerve and surprise us with a special guest referee nobody saw coming: Bray Wyatt. It would be a very random choice, we agree.
WWE has no plans for these former AEW wrestlers? Here's why!
But it would also be a great way to add interest to the match. We already saw Rollins vs Corbin at WWE Super ShowDown 2019 and there was no interest then. There still isn't any interest in the match, which is why Wyatt being added spices it up a bit.
