I think he already has signed, or at the least it's a "we'll sign you when you're healed up" kind of spoken word deal.
I'm not a fan of the guy, so I wouldn't want him there. He's not the best talker, not the worst, but that's about his ceiling. He'd probably make a decent undercard hand, but they already have guys like that.
He promotes AEW on Twitter weekly and has been setting up a match with the Ass Boys for a while now. If he isn't getting signed then I would be shocked. It would make him look pretty desperate. He is one of the hottest merch sellers out there that isn't signed to WWE or AEW. You can see his shirts at every Dynamite. Just like OC, there is money in a guy who commits fully to his gimmick and is entertaining to a large audience. Danhausen has more variety to his stick compared to OC though.
