I was thinking that would be a great idea when Noirin was still in the house. It would have been great to pretend to evict Marcus but just send him in another room where he can see and hear everything for a couple of days while everyone bitches about him. And then have him come back in and have everyone be afraid of him for knowing what they'd said lol.
I think right now it would be good to do that to Freddy, so he can see Bea for what she is, but most likely, none of the housemates would believe he was evicted because they think he's so popular. But anyway, if that bedsit isn't there anymore, they can't really just build a new one because the housemates are next door.
I really wish they'd do more things like that though, like have the public vote to bring back one ex-housemate. Imagine the look on everyones face if Noirin walked back in lol. Or have a new housemate in the show. I know people think it's too late now, but I think they could have someone come in who would be really exciting, that BB could guarantee the public would like and be able to live up to there profile video. Then they could have him/her up for a eviction for like the first 3 weeks in there to make it a bit more fair, and that would scare the housemates if they were kept in all three times.
And yes, I think there would be the best bits from over the last ten years of BB if it got canceled. BB10's the only one I'vee seen properly though, so I don't know what the others were like really.
Sorry, that's a long answer ( =
