Alex winning would not be that bad at all.
Vinnie would HATE it.
Jordan would HATE it. (it would make him legitimate in the public eye on his own merits)
He may be dim but he has generally been a good egg and has stood up to Vinnies crap.
He's not been a boring housemate.
From being the most reviled housemate going in to winning the thing would actually be a interesting twist after so many boring winners.
