I take comfort in the fact Adam saw the official Blu-ray release of the Batman TV show, along with a resurgence of the brand via comics, animated movies and various other merchandise.
There was also a sequel to last year's "Return of the Caped Crusaders" planned, with William Shatner as the voice of Two-Face. I hope Mr. West completed his voice work before he passed.
And if you've never read DC Comics' "Batman '66" title, I highly recommend it. It's a loving and faithful expansion of the West Bat-verse, featuring popular villains who never appeared in the show itself or were introduced years after it went off-air.
