I think that since all of the former cast of Gilmore Girls is now free, that Amy Sherman-Palladino and her husband should change the name and continue the story. They have created a world which the witty and intelligent among TV viewers sorely miss. If they act quickly before the primary actors are committed to other projects, the spin-off would undoubtedly be the most successful spin-off ever.
Since Rory's going off to seek her fortune and Lorelai married Christopher... even though they split back up again, Gilmore Girls would have been an inappropriate name for the continuation of the saga anyway. A new name would bring freshness to a series that never seemed to lack it, until it's creators were forced to leave the show, which no doubt hastened its demise.
I have no doubt that this could be one of the best casts ever to have been assembled, and would hate to see it broken up just yet if a smart network would urge Amy and Dan to pick up their characters and return them to their rightful place: in our living rooms!
