Uday Kaul or WP Saha.
I really don't see wholesale changes being made, much to a lot of annoyance. Ojha, Ashwin, Ishant and Yadav all did well at least at one point through the series. If Chawla is next cab off the rank than neither of them have too much to worry about.
With batting there are a lot more options. Mukund, Vijay and Rahane could all come in at the top and Rahane, Badrinath and Rohit who could come into the middle order. Hell there's Yashpal Singh, Nayar and Tiwary too.
