Nunavut operates under a non-partisan concensus-style government where the premier is selected by, and from, those elected to their Legislature. I have serious doubts whether that style of governance would be effective on a larger scale or in a different environment.
I think Canadians are smart enough to see through Martin's rehortic (at least I hope so, anyway), and if they aren't, I'd be surprised if enough Canadians cared about parliamentary committee structure to pay attention.
Canada has seen power centralised in the PMO and influence removed from the individual MP. However, if has not always been like this, and it won't always be like this either. Does the political will exist in the Martin government to make real democratic changes? Of course not: all Martin has ever wanted was power; why would he change the system that got his that? It's going to take a government with the political will (and a campaign promise) to make changes in the democratic direction. We're not going to see that if we keep electing the Liberals.
