Sure, and snorting vitamins could replace eating meals. Sleep has been implicated in a lot of secondary roles, including memory consolidation, the body's ability to repair itself, etc. It's unlikely such a fundamental process can be easily replaced.

Sleep is also implicated in muscle repair, aceytlcholine turnover (related to memory formation and muscle power output) and ... well ... pretty much everything.

If sleep wasn't performing useful functions, it would have been selected against ever since higher animals evolved.

Unless, of course, stumbling about in the dark and unable to see while bored out of your skull because you can't sleep posed some sort of risk.
