I think Thor's plan is a Proof-Of-Concept, intended to show everyone the potential of a 4Q Patch SystemŽ, with the long-term logistics being a problem for the production staff to work out.

Because, when this is all over, Thor is going to drink a beer or two and relax an ocean of beer and pass out for a decade or two. He won't be that worried about what they do with the other gates, and would be in no condition to help anyway.
