Unless things have drastically changed this application cycle nominations cannot be shared cross state. IMHO that would get really political.
I have heard, may not be the case this year with it being so competitive, that if the Academy wants someone bad enough the Supe can nominate.
Side note: Had one candidate who was not picked up in the '11 go round who left our state to go to an out of state college. Parents were no longer supporting candidate when he reapplied for '12 and he had declared residency in the new state. Could not go back to his home state to seek a nom. Nomination must be sought from the state of residency.
