Replacing Ajinkya Rahane by Ravichandran Ashwin will make much hardly any difference. The latter is capable of scoring as much run as Rahane. In addition you have one world class spin bowler.
While Jadeja might have bowled well on the last day he was below par on Day 4; Ashwin might have performed better and in both the innings at that. I would bring Ashwin and Suryakumar in an dleave out Siraj and Rahane.
