Love Worf and all but, yeah, no.
First off, I do not think Worf is Starfleet Captain material. He's awesome at being a right hand man, he will always have your back but he is not a good leader.
And I agree, as compelling as Worf was, Michael Dorn couldn't carry a show.
Worf has had more screen time than any other ST character and DS9 left him in a great place (BTW, I refuse to believe he left his position in the empire as ambassador to go back to pushing buttons for Picard on the bridge. In my mind he was just there for the wedding and stayed for the adventure.)
And frankly, Michael Dorn is getting too old to adequately portray Worf, it was noticeable in Nemesis.
