Yeah I bet there would be enough supporters to retool a Flagg if it was in the $600 or s range. It would be cool to see just how many people would be willing to make it happen. I know I would be in for sureI think the Whale or GI Joe Headquarters might work, but the Flagg would probably have to be retooled and even then it would most likely cost $600-$800. The production of the Castle Grey Skull set was also contingent on the number of pre-orders MattyCollector received.
It is a great idea though - The Flagg could be topped off by several planes, and maybe 10 joe naval figures.
