That's a great idea. The heavier your armor, the faster you tire.

However, Mithril armor is ridiculously light. But for a suit of Mithril plate armor to give such excellent protection, it must clearly cover all parts of your body. So maybe Mithril can have a separate penalty, related to how it restricts movement.

Heavier weapons could also inflict a fatigue penalty. The fatigue should depend on weapon usage and movement while wearing armor.
