I have a novel that has been rejected from on high by all of the major NY houses. They praise the book, but don't want to publish it because of certain political sensitivities.

I think that UK publishers would be far more receptive to it. Before I even raise this concept with my agent, I want to ask if this is the stupidest idea anyone has ever had. Has anyone ever taken their book Across the Water, been published, and then successfully re-invaded the US? How would one go about this? Would an American agent be wholly resistant to the idea?

I've nosed around the web a bit, and can;t find a shred of information on this topic.
