Basically to while away a few weeks in late spring, You would have say 4-6 Celeb couples.

Either you would pick two at random or even real life celeb couples

You would have two of the pros as coaches to each couple say
Brendan and Karen ect.

Maybe last over 4 weeks on a league basis no vote off until the final.

Basis of an idea or recipe for blood on the dance floor ?

Ohh Yeah
