If they simply do one or two episodes within a full 12-13 epi season Stateside, then that would be, as you said, shiny. (If they had to up that to three or four simply to justify the cost, then I'd live with that as well, although didn't they actually fly folks to NY for Daleks in Manhattan etc. in S3 of DW?)

Brent Spiner as a senator? Kewl! Make him a secret alien and possibly eeeevil? That would be even kewler. Or make him a secret alien fighting other even more secret aliens with Torchwood, and I'd be so on board they couldn't throw me off upper deck.
