I've been thinking about this since I saw your post and "plotting & planning" out a design. I'm pretty sure the brick weave made with 360s (and/or 321s) would work for the wings. Since the pattern in the brick would be staggered anyway it wouldn't be that hard to manipulate the colors so that they resemble the patterns on the jet. The wings could then be firmed up and made more stable (less likely to bend) when you go around the edges to clean up the ends. Also, it might even be possible to hide a light weight support rod in the wings.
Since the brick weave is based on horizontal bubbles of the same size, the only part that would pose the biggest concern would be how large to make those bubbles - too big and you wouldn't have enough design room to get a decent color pattern going - too small and it causes lots of extra work and the sculpture doesn't last as long. I'm thinking a wing would be about 9' long. If you used 12" bubbles you should be able to get a decent pattern because it would give you 9 color change opportunities.
Brick weave as seen used for walls at Balloon manner:

Good luck and looking forward to seeing what you come up with.
