Sounds like a fun concept. Here is how I would promote the event, using only the names you provided in a company feud scenerio. Vintage guys' pictures have a yellow glow and are on the left. FUW guys' pictures are on the right and have a blue glow.
*FAKE-EVENT*

Kahagas and Bruce Santee put their respective titles on the line against Beast Mode. I picked these guys to Main Event because of size and titles. Any pin means a title change. I would allow Kahagas/Santee to pick up the win with botched interference by Solo. They become Vintage tag team champions. If Santee and Kahagas never work a Vintage show again, I would have them be stripped of the belts later because they refuse to tag together again, playing up their potential NWA feud against each other.
Lince vs Cruz - I don't care who wins. It is a good match.
Angel vs Beasley is the hardcore match of the night. I assume there would be plenty of run ins by team Vintage and team FUW.
Chavis vs Tarver would hard hitting. Leva is the referee. Her assist as part of team Vintage would allow Kory to keep his title.
Ciatso and Young is put together solely because they are very talented heavyweights who rarely wrestle each other.
Wes Brisco is featured as an appearance because I didn't have an even amount of male talent on the card.
The North East All Stars vs NVUS could be billed as two great tag teams returning for their respective companies. I thought that was a good way to round out the card. I assume Simon and Cooper could do a DX reunion type of segment before the match. They were only left off the poster because I ran out of space. No offense to them.
