I honestly think allowing the sisters to be apart will mean for better viewing, because they could turn on each other.
I'm doubtful they would, especially if they don't usually. My friend has girls a year apart and those girls once spent 4 hours on the thinking chair because one just would not sell out the other. They stuck to their story to the very end. My kids turn on each other before you even ask what's happened.
