Here's mine:

LOST IN SPACE would basically be LOST...except in space. A seemingly random group of people whose ship crash-lands on an artificial planetoid that itself moves through space, traveling from star system to star system. Mysteries would abound as this group of survivors seeks out the truth of the planet.

KOLCHAK THE NIGHT-STALKER would be similar to the original, except with a much faster pace and with an underlying bigger story from season to season. Kolchak himself would still be an old bastard, but not quite as old. Perfect for a character actor. Perfect for skewering shitty modern takes on vampires and werewolves like Twilight. The only real vampires in this series are mindless monsters who prey on human flesh rather than aristocratic types or teen goths full of angst.

SLIDERS would basically follow up on the original series except with a much bigger budget. Given the fact that The Defenders was cancelled, Jerry O'Connell might actually be available, except in a more mature role. Instead of seeking home or battling aliens with sliding technology, the original Sliders have by now become the puppet-masters pulling the strings on several worlds. But a new group of Sliders, learning of the originals' existence, seek to take them down and free the multiverse once again.
