In all seriousness, if Katich isn't picked to open ahead of Jaques, I really do think he should play in the middle order instead of Watson.
While I am a Watto fan, a test series in India is not the greatest place to make a comeback.
Not sure if his bowling in a country that is notorious for spin, is worth him being the all-rounder at 6 - and I'm not sure if he'd be that great with the blade, either.
Simply put, if Australia want to give the next generation guys like Watson, Johnson, insert spinner here, or the like, experience in a tough place like India, then by all means go ahead. I would understand that if it's their aim.
But if they want to win the series at all costs, I'd be going in with Katich at six, McGain as spinner and perhaps Noffke the third seamer.
Watson is probably best served making a test comeback at home versus a rather new and 'soft' adversary in New Zealand, in preparation for the South Africans, giving him some good experience ahead of the 2009 Ashes, IMO.
Can see him either getting injured in the heat, or suffering with bat and ball, and subsequently missing the home series.
