The door gaps look great, better than Ford ever did. Ford liked the doors closer to the front fender and larger gap in the rear and a wide gap below the door. Make sure you get the softest door seals you can find. With tight door jambs you may have issues, allot of people have had issues. My only concern is moving the pivot point of the hinge a 1/4" or more back and how it may or may not cause issues in the striker. The door latch is going through the striker at a slightly different angle than intended. The original hinge pin is almost in line with the edge of the fender and you have moved it significantly rearward. I doubt you will have issues but you don't want to find out after its all painted.
One thing you may want to watch for is Ford could have used out of spec bodies for the roadster knowing that tops and doors are not going to be attached. They also didn't live their life with the support and structure that a metal top and solid doors give so the sheet metal has allot more room to move on its own.
