I'm in the process of swapping the pilot for an HG ν Gundam, but I'm using external parts to address the lack of strength in the hip joints.

I'm replacing the polycap inside the HG's joint with an external part, completely removing the internal structure. The external part fits perfectly. I trimmed the external part to match the diameter of the cover section on the HG side.

This allows for connection without modifying the Azeryus's hip joints, and the strength has also increased.

However, the external part fits too snugly, so the legs can only move forward and backward; they can't spread outwards.

I'm using the HG to this extent because the RG ν Gundam is too valuable to use, and the HG is sold at stores...
