So I attempted doing this about 6 months ago, but my troubles with the Shapeways head and the original neck joint forced me to use a different upper body.
Originally composed of about 50/50 Classics Mirage and Universe Dragstrip, he's now about 80/20 with the only Dragstrip parts being the arms and crotch piece. If I was able to recreate the red stripes on the shoulders myself, I would make it closer to 100% Mirage.
Eventually, I'll get the Shapeways head for this figure to finish the 'transformation'. I love the Wreckers and unlike Scoop, I don't really see the Rotor Force getting a Generations reboot.
Enjoy
