Primitive substitution in the minifig arm

[Gerald Lasser]

What will happen to the position of the grip in the hand? Does it also move 2 ldu? Could we make the wrist longer?
Could you please add a ldraw hand in your picture.

Yes, the grip needs to move back as well.

The wrist is a tad too long, but that could stay IMHO

Changing the Elbow + Lower Arm, but extending the wrist would do no good. The wrist would be far too long, even if the geometry would then be fully backwards compatible.

Now one thing comes into my mind:
- Compatibility to the handles, Steering bars, hand cuffs

I tested this and even wit the shorter elbows that should work out.
