As part of twists, housemates have been paired for the week (in BB7 - even evicted as a pair - Spiral & ?, BB11's horse task etc.), but how about pairings for the majority of the series?
Housemates can either enter as friends/relatives, and everything they do are in their pairs - nominations, tasks, etc.
OR
Housemates are immediately paired as they enter the house by random (some sort of 'name from the hat' system), and they do everything from then in their pairs.
I think this would test individual's popularity - will somebody loved be kept even though their pair is an asshole? Nominations will be difficult, as pairs may have alternate opinions + you may hate somebody but are you willing to nom them if you like their partner?
Half way through the pairs can swap or they become single housemates.
Evictions could either be done in pairs, or single evictions which split pairs through the show, with the last pair winning some sort of prize - maybe half the prize fund?
Just an idea, I wouldnt want it for the upcoming series but a possibility for next year's
