That would be a great idea,

What they could do on launch is have the typical BB10/BB9 Entrance and when they walk in they face two doors like in BB9 when Heaven and Hell begun.

A sign in between the doors says;
'It's Your Choice...'

And it's up to the housemate what door they walk in, one door leads to Heaven/Rich Side and the other door is Hell/Poor Side.

They should be seperated by a huge plastic see through wall, that shall be soundproof.
Outside, they're seperated by a small fence like in BB9.
The divide is changed every 12 Days and is decided by a live task after the Friday Evictions.

The advantages/disadvantages should be far more extreme, like for example:

Poor HMs are woken up by having Cow Sh*t dropped over them in bed, or cold custard or something.

Rich HMs should be able to nominate 2 Housemates whilst Poor HMs can only nominate 1.

The divide should last for about 6 Weeks out of 13.
So about half the series is divided.
