It is a win-win. Other than budgetary constraints of having her fight to the death too, I see no reason why that could not have been a brilliant solution instead of having her in the background to sub in for Kitty if the time would come.
There are many things Rogue could have done in this movie, but just like in X3, Anna Paquin simply wasn't available for an extended role. There is no way they could have shot such a huge action piece in just the few days she was on set.
