They lost their first 2 games on similar fashion because of batting so they should fix this one, they need stability on middle order. Bowling seems okay so they could compromise with 1 foreign allrounder. Pick 3 pure foreign batsmen (Warner, Bairstow and Williamson) + 1 bowler (Rashid).
And may be pick Sidhart kaul if they think their bowling is weak because of 1 less bowling allrounder and let Shankar sit out for few game, he's failing on both department batting and bowling.
I am OK with the suggested changes, but it looks as if David Warner and the rest of the SRH management don't want to drop Jason Holder. And I can't blame them because he has bowled really well during the depth overs. And although he wasn't much impressive with the bat, he can be quite handy in crucial circumstances. BTW, what about replacing Williamson with Bairstow? I would say that the former is a much more useful batsmen when compared to Bairstow.
