The aspect of hybrid shows that both straddle genre and comedy are tricky on network television, not because of standards but because of tone, budgets and approach. "Ghosts" in its pilot suffers from this to a point but many shows simply have become an interesting exercise (see "Brain Dead").

Coming back to the place where it all began but making it make sense to do so with the stakes requires a bit of movement while not losing the angle overall. It is a tall order...and even more tricky for a show like "CSI". Finally coming back home to its Vegas roots with "CSI: Vegas" always required a return to arms of a certain person.
