This completely. "Dedicated to Leonard Nimoy" would be great*, Spock should keep on livin'.
Or maybe more? Like "Dedicated to Leonard Nimoy, Grace Lee Whitney, and all the family we've lost along the way..."
For me this, either a specific dedication to Leonard Nimoy if they want to just note his loss last year or if I were doing it "In Memory of Absent Friends..." as a dedication to Gene, Majel, DeForest, James, Leonard, Grace and anyone and everyone else who appeared on and off screen (like Matt Jefferies).
I liked when they paid tribute to General Hammond in Stargate by letting the character pass the same way as the actor and naming a ship after him... just not in this case.
