Couldn't they do a separate 'flying' head that only looked good in a flying pose? It wouldn't even need to be a separate sculpt, just a retooled version of the main sculpt, although I would want a stand that allowed the figure to 'fly' - something like the Sideshow Thunderball Bond stand.
well it could be engineered like the DX batman head by having the head attach to the neck via magnets. that way you'd have the sculpted neck and would be able to pose the head in a looking up flying position
