The cleverest way to bootstrap (handle initial distribution) imo would be to allow people to buy in to the new chain by destroying their bitcoins in a specified manner to 'move' them into the new chain. But really that is just a way to allow people a one-way ticket into a breaking change version of Bitcoin, not a completely new system.
Bitcoin isn't really working. I've been around here for a long time now and still don't see much growth in real economic activity outside of speculation. This might be fixable with a better distribution scheme.
IMO, cleverest way of handling initial distribution is to force miners to give away money to merchants who agree to accept the currency. Starting will small-time merchants and working up gradually to more important merchants as the currency becomes more valuable. Possible mechanism described here:

Of course, bitcoin tries to do this through voluntary participation already. It is clear fail. People don't volunteer to give away significant amounts. You need to compel them.
Ok, me me me I'm a merchant.
Maybe it is a clue that people are speculating that it's going to get a lot bigger? They don't spend money for no reason you know.
