There is this concept of housemate exchange in Big Brother which has never happened in India in 13 years.
They swap housemates from two houses from two different countries while the show is running. It has been done a lot, like from BB-UK and BB-Africa, BB-Netherlands and BB Philippines, BB-Thailand and BB-Sweden, BB-Argentina and BB-Spain and so on. It has been many many times.
Contestants are usually swapped for 1 week. Audience are shown some highlights from the other show from which the contestant is coming. It brings an interesting "twist" to the "story line". There is cultural exchange, dynamics change a lot as there is a sudden break from ongoing relationships and strategies.
Do you think BB India should also think of this and try it out? BB-Poland and BB-Spain is also going on at the moment.
If not another country then maybe from another BB house in India. BB-Kannada is also going on currently.
II would love to see this happen in Bigg Boss India. It is like a semester abroad during college.
