>>9921061Good question. I just tried it and the Lego hand goes two-thirds of the way in before it gets tight.
You might be able to force it in, but I didn't want to risk getting the part stuck. It seems to be getting caught on the little ridge below the wrist so if you're open to some heresy you could sand that down.
Alternatively you could try getting away with having dudes with extra long arms/ill fitting jackets.
