To be honest, I probably would buy something like this if it could be broken down into 10 or more stages/sets to keep the overall cost manageable. Your stunning work has me sold on what could possibly be one of the hottest fan made/designed items I've seen in some time!
I was really hoping Yamato would do a 'bells & whistles + everything but the kitchen sink' 1/24 VF-1 ultimate version collectible w/A,D,J & S head variations, and swappable dual-seater cockpit included, but I'm delusional like that .
So yeah, I'd be totally down for something like this done in an affordable way. At the very least, I hope that you can do the other head variations in 1/24. Would make for one hell of an awesome display!
