The easiest solution would simply be to get a 6x7 or 6x9 rollfilm back for your view camera. Of course you still get a MF sized negative (my 6x6 ones from Pan F+ print beautifully at 15x15, with invisible grain, so I'm sure a 6x7 would go to 16x20 without issue) and you may run into short lens issues when you need wide angle, but for many shots it will give you the movements and workflow of the viewcamera with Pan F+. I use a 6x7 back for color myself. LF color is simply too expensive and too hard, and expensive, to get processed, and I don't do enough color of any kind to bother with it myself again yet.
