I really don't mind if he doesn't make the cut though, there seem to be plenty of bowlers in the mix and it's the least of our concern at the moment.
I had high hopes for Copeland, but quite a few Shield batsmen predicted he'd have a tough time backing up this season, and so far it looks like they might have been right. He's averaging 124.0 after five innings in the field, with a truly horrific strike rate of 345.
As you say, though, bowling is (remarkably) not our major concern.
I'm actually not convinced there are enough good young batsmen out there for us to build a strong Test team: not now and possibly not even in 2-3 years' time. Assume Hughes and Warner come good long-term - seems reasonable despite their current weaknesses, given their obvious talent and work ethic. Clarke and Watson are at least "decent" batsmen, and could be remembered as being very good indeed if we're able to shield them from the new ball with strong openers.
That's four. Who else fills out our top six in the next Ashes? And where do the 3-4 backups come from when the top six are injured or out of form? Players like Chris Lynn, Nic Maddinson, Mitch Marsh, Kurtis Patterson all have potential. Problem is that they don't have 50+ averages, which at one time was a pre-requisite for Test debut. They're all averaging 20-30 this season, which isn't a great trend.
There's every possibility those guys come good. But they haven't come good yet - which means we face a tough choice against India. Either we keep blooding young batsmen in the hope that it'll accelerate their development, or we field older journeymen cricketers (Cowan et al) to win the series, so that we don't have to listen to Indian fans rabbiting on about how they beat Australia in Australia.

I think I've talked myself around to having Cowan in the XI after all. Send Mitch and Maddinson to Worcestershire, if they want to accelerate their development.
