Was thinking about this yesterday, but India might have a long term problem replacing the veterans because their younger players don't get exposed to grassy pitches enough. With the IPL, it's very difficult for Indians to play county cricket, and with 2/3rd of their matches in Asia (counting their own and tours of SL, Bang - UAE I guess) it's hard to get that international exposure to different conditions.
On the plus side for India though they will always produce a lot of talented kids and sometimes that talent will outweigh the problems that inexperience in seaming conditions might provide. It will be an interesting few years ahead anyway, once the big 3 retires.
I like this. If you can separate your Test and limited overs attacks then I think it's a good plan. One reason is because if Siddle/Hilfy get spanked in ODIs/T20s, then their aura when they play Tests is lessened a bit. Another is the one you pointed out, they start practising skills that are crap for Test cricket eg. slower balls, back of a length balls that feed the cover sweeper. If Harris, Lee, Johnson, Bollinger, Hastings and McKay became your short form attack you could leave Siddle, Hilfenhaus, Cummins, Pattinson for Tests. It's worth a try I reckon.
