My support to Ashwin is on the basis that we do not need 3 left arm spinners in the side- the attack is too one-dimensional. Both Axar and Jadeja are containing bowlers. With Ashwin or any other right hander you can negate the left hand batsmen to some extent. My backing would go for Ash/ Washi. If neither is available, Bishnoi is an added unknown that can be tried out. With Ashwin though, you get a stable head and some one who can bat far better and consistently than Jadeja or Axar(probably combined). I am not going to go by averages like you have, cause numbers can't justify the potential of a player. Perhaps, the team management too is thinking on similar lines and hence the chances to Ashwin in the coming games? Furthermore, you cannot discount him on Indian tracks.He is a handful- no matter the format.
Alright this is utter satire at this point, especially when Ashwin is supposed to be the equal of Jadeja and Axar combined with the bat while he bats behind them in most instances across formats today and because there is hidden potential in a thirty-seven year old.
