I sometimes fantasize about doing a mild custom 2nd gen and that would have been on the list of mods.
But....I remember reading an interview by one of the Duster designers. He said other than the short time line and lack of money (typical Chrysler), the most difficult thing was accommodating the extremely curved side glass. Trying to fit it into the door depth was the problem. IIRC, it was the first time a side window with that much curvature was used so I'm guessing it would be difficult, though not impossible. Also, the 67-69 windshield angle is way more upright than a Duster.
