It will take more memory in the case of small integers, but also improve performance for integer linear and polynomial algebra. I think the improvement would be worth the added memory consumption. Granted, for some purposes this might just be added memory use for no gain.

Could you support packed arrays of 64-bit integers as a special case 
without doubling the size of all machine integers. If you doubled the 
size of all machine integers, I imagine that could impact badly on a lot 
of user software.
