Has anyone done a successfuly modification to Crosshair's wrist (or both wrists)?

I had an Elite force fella with a swivel wrist and it fell out (broken!!). I found my tiniest drill bit and drilled out the hand/wrist and forearm. Then I took a standard Joe screw and clipped the head with a bolt cutter... Then I slowly used that fragment screw to reattach wrist and forearm. It worked and the wrist has the advantage of swiveling, which got me to wondering...

...Could we cut off Crosshair's wrist and do a similar operation on him?

I only have one Crosshair, so I'm a little leery of doing this. But it has the potential of significant added poseability/articulation.

...Or ruining one of my best figs forever...

If someone else has already tried, let me know how it went...

Thanks!

Joe
