Oh, my, yes! Mmmmmm, six seasons, all on CBS, with a normal timeslot and not part of the Crimetime After Primetime rotation... and Lacroix could stay dead until, say, the fourth season, if not forever, and the original actors leave only if and when they want to and with plenty of warning to write out their characters well... ;-)

My current hypothesis is that the fictional Vampire Cop show is probably a versatile mash-up of Angel (young adult, long running, successful, well-known) and Forever Knight (smart, award-winning, actually a cop-shop show), with the "Brandon Acres" character probably drawing mainly on David Boreanaz while the show itself draws mainly on FK.
