It's amazing how a little plastic goes a long way, what with how significantly those filler pieces improve Jetfire. If/when I get one, I'm certainly popping you an order. Though on the same subject, maybe you could look into adding an upgrade to the old Jetfire Voyager model for your offerings? One of the key flaws of that mold is that the feet are little more than the slightly pulled apart jet engine nozzles, which in of themselves are hollow shells so they do an absolutely horrendous job of keeping the figure up if the center of balance is shifted even slightly off center (such as sticking the giant booster rocket/cannons accessory on his back and not keeping the cannons deployed over the shoulders). I'm not sure how you could pull it off without partsforming, but even with that concession, the feet parts might be able to then slightly change shape to become covers for the figure's hands in alt. mode which normally don't have any kind of means to not be obviously robot hands beyond simply sticking the gun halves in, which doesn't really do much when looking at the jet from any angle other than head-on.
