I wonder how much weight an effective design would add. It would probably need to be made out of some decent material, which would probably drive up the cost.

Aluminium would probably suffice, I doubt it would add more than a kilogram even if made of steel. You need an articulation that can hold let's say 150kg for an overweight person putting all their weight on one leg. It is not a crazy mechanical constraint. Bikes handle more with lightweight structure and more complex mechanisms.
