I need help on my figure's hands

Posted in Custom Workstation

Hi, I'm making a Mysterion (South Park) figure and I wanted him to have two sets of hands - a pair of DC Universe Classics 'The Spectre' hands, and a pair of fists from another figure in the DC Universe line. Obviously I want him to have interchangeable hands, but I don't know how to do it. There's no way to rip out/pop out hands back and forth without some bad effect occurring. So, could you help me? I need a way to convert the figure for interchangeable hands. Thanks!

P.S. I'm only using figure parts from DC Universe Classics lines.
