I always thought the most interesting story that could feature Shatner as Kirk, would've been to place Storm Front
forty years later and in that reality Kirk, Spock and McCoy never escaped the 1930's from City...
. Archer would've teamed up with an elder Kirk who was now running the mission in Nazi occupied New York.
Before the timeline gets set right, an elderly Kirk gets a chance to step foot onto the NX-01 bridge and sit in the captains chair one last time.
