[One Piece] If a bounty hunter SOMEHOW managed to capture one of the Four Emperors and collect their bounty, what would the economic impact be?

So suppose the unthinkable happens: some crazy strong bounty hunters manage to take down the crew of an Emperor. How does the World Government pay them? Does the WG have a few billion berries lying around? What happens now that these bounty hunters have what is basically a small nation’s GDP in their bank accounts?

Seeing as how the World Government regularly increases the bounties on the stronger pirates by millions (or billions) and they have the resources to construct massive sea fortresses and also have the backing of the celestial dragons, They can afford to easily pay off the bounty of a whole emperor crew without excessively damaging their accounts. 

It honestly depends on how much monetary support do they get from the celestial dragons. If they're allowed to use their money freely, then the world government can easily pay off the bounties of 4 emperors and their crews.
