I like Michael Dorns idea for a series. The timeline he wants is messed up though. it should be placed after nemesis. Probably wont get made but it would be cool to see worf back and in command. Link below.

I think 'Captain Worf' would be DOA. The character has been way overused in universe.
But we never have had a Klingon Starfleet captain. I would be interested to see how Worf handles being a captain on deep space missions.. It would be cool to see if anything Picard taught him stuck.
It would... otherwise he'd be courtmartialed.
