I'd love to see a season of Top Chef with previous cheftestants. Put 2-3 from each season and give them a whole season with challenges designed to showcase their talents. My roster would include:
Season 1: Harold, Leanne & Dave
Season 2: Sam & Cliff
Season 3: Tre & Brian
Season 4: Stephanie & Richard
Season 5: Stephan & Carla
Who would you like to see compete in Ulitimate Top Chef?
Oh and what kind of challenges would you like to see? Personally, I'd like it if they had the same ingredients and had 30 min for the quickfire. Less catering challenges. More time/money/stores for the cheftestants to plan and prepare, let them show us their best work without alot of contstraints.
