If they were to repackage this guy, I'd like to see a slow return to a few goofy gimmicks for the WWE (ala mid nineties) so I would make him a restaurant critic.
Dress him up in a tweed jacket, tanned slacks, spectacles and a monocle.
He puts on his best upper class british and talks about his love of fine food at first..
Give him a segment called 'Mason's Culinary Review' where they set up a table for two in the ring and serve Mason and his guest (some random lower card wrestler) some high class food.
Everything is going well between the two, Mason has a mic and gives the food a good review, but then his guest accidentally spills his wine or messes up his cutlery or something.
That's when the crazy insane side of Mason comes out, he loses his temper over the besmirching of his food. He flips the table over, smashes his guest's face in, then hits a big slam/powerbomb, whatever through the table.
He rips of his clothes and shouts at his victim "Don't mess with my dinner!!"
Run this for about 9 weeks or so, with a few matches in between. The segment becomes a hit because the crowd will be anticipating Mason flipping out and watching the monocle drop from his face before the beatdown.
The rest takes care of himself. He can beat HHH at WM to solidify his spot. Then him and Triple H could form a tag team reviewing food from around the world and each segment ends with a bar fight with the employees of the bar. THE RATINGS WILL SKYROCKET!!
