Anything is possible, but man you love to make a lot of work for yourself haha. I would seriously doubt anyone has done it so you are on your own as far as design...
I would guess since manual windows have not been used since the 80's in Ford trucks, you would have to rig your own operator, but it would certainly be possible. Look up some designs of manual window regulators and see if you can use the scissor design that the current ones do, that way you don't have to worry about fitment issues.
EDIT: Was interested if you could so did the google search for you, now just have to find the geared parts...:

A scrapyard can get you a used window regulator for 20 bucks, and it takes ten minutes and a second set of hands to install. To me there is nothing better than driving with all the windows down and it would be a pain to have to walk to each door individually haha.
