But if you need to, I may imagine it would prove to be more secure to go directly to F, check in and clear security. If there's any delay in clearing security, at least you're already checked so the departing plane knows you're coming... right?
Assuming you're checked in before your first flight, there would be no need to check in again at F. FYI, the walk from A to F landside would be completely outside (although I guess you could walk into D, over to E and then on to F...actually, that option gives you the chance to look at D/E security and possibly go through there).
US might consider this a legal connection, but I would prepare for the worst. Hope the arriving flight is early, CBP is empty, and the departing flight is late.
