You know, this isn't a bad idea. 8 tag teams may be too much though. Maybe 6 tag teams. The mentors could be: The Dudebusters, Archer & Hawkins, The Hart Dynasty, The Usos, Koslov & Santino, and Goldust & Yoshi Tatsu.
Heck, you could even pair one team up with Laycool, or the Bellas just like they did with Kaval on season 2.
It's definatly a possibility.
