As long as you have to interface with "the fiat world" for income and spending, this sounds like more trouble than it's worth. The gateways (fiat->btc, btc->fiat) know your identity, take a higher fee than banks and you still have to trust them. Additionaly, you now have the risk of varying exchange rates at multiple points in your money flow. As for the global bitcoin adoption, I don't see this approach helping at all. If you think of yourself as a node in a global economy graph, you still take fiat as input and produce fiat as output.
