Unfortunately, I think Alex moving from a CBS show to a CW show is about as likely as him moving from Hawaii to Vancouver or Atlanta (the cities where most CW shows are shot).
I would love to see Jason leading his own show. The CW does seem to love him, so maybe they are just waiting for the right project -- as the TV Line article points out, a lot of the lead actors on CW shows started out doing guest roles in other CW shows.
My ideal project would have Jason doing noir in the style of Raymond Chandler's Philip Marlowe mysteries -- either an adaptation or inspired by it. I got into reading Philip Marlowe after finding out it was one of the inspirations for Angel of Vengeance. (I had already read the other inspiration, Dracula.) Jason's voice suits Chandler's writing style perfectly -- I can't help hearing Josef's voice in my head when I read the novels. For example, here's the opening paragraph of The Big Sleep:
It was about eleven o’clock in the morning, mid October, with the sun not shining and a look of hard wet rain in the clearness of the foothills. I was wearing my powder-blue suit, with dark blue shirt, tie and display handkerchief, black brogues, black wool socks with dark blue clocks on them. I was neat, clean, shaved and sober, and I didn’t care who knew it. I was everything the well-dressed private detective ought to be. I was calling on four million dollars.
Don't know if this is still in the works, but the CW is/was actually developing a Marlowe-esque TV series. Unfortunately Jason doesn't suit what they have in mind.
