how about making it family BB
we would have 6 families each having 1-3 kids for a total of 24 HMs
there would be 1 large bedroom for the parents with and 2 small bedrooms for the boys and girls
for tasks one week we could have the families against each other, another week have all the parents vs all the kids and another week all men and boys vs women and girls etc
for nominations sometimes might get a kid nominating one of their parents or vice versa
also activities provided would be things like a parents night where they go to a large task room that set up as a bar alcohol music dancing etc
for kids could have things like xbox/ps tourneys and summat similar for girls like horse ridin lessons in the garden
so basically it would be just same as normal BB but with added dynamic of the family
an example for first series could be
1. a white middle class family
2. an asian family
3. a black family
4. a white working class family
5. a celebrity family
6. and a family from hell !!!
it would have massive potential
could have a romeo and juliet style romance instead of the usual snoremances
might have some epic comical bitching from kids about the parents
imagine a mini rex or a mini charley
