With no Watson and Martyn, you'd imagine two places in the side would be up for grabs. Jaques and Hayden fighting it out for the second opening spot, and White and Hopes to bat at 7 and bowl a few overs. I can't see them going back to Hayden again, so Jaques and Hopes would be ahead, I'd imagine. White's had a great run this season too though, and I'd rather see him at 7. Hopes will never be anything more than a handy ODI player IMO, whereas White could be genuinely good, particularly if his bowling improves a bit. And more to the point, Hopes would be better served batting in the top 5 than coming in at 7.
Because of that, another possibility would be Hopes in as an opener as a direct swap for Watson, and Voges or Cosgrove or someone in as a specialist batsman.
