That mod would be really easy to do. All you really need to do is re-draw the formers forward of the windscreen. You could actually just blow up the nose section of the picture you have for the outline. Then you would have the scale length and you could draw the top profile by hand. Now you have height and width measurements for the formers. Then it is just up to drawing them. That is what I did for my turbo commander nacelles. I used Adobe illustrator and Paint to fine tune them. You really only have to draw one half. Then you scan it into your computer and mirror it. Now you have a completely symectrical former.
