Adding amputated leg items

[Glamurio]

Would have to be limited to a selection of items, the balance implications are huge

Yup, totally agree. In fact like we mentioned, you shouldn't even be able to use most of the items, they'd just be stuck to your leg as any limb, so it'd be even worse than getting them attached to your arm. But programming some unique interactions with a few items (mops, chainsaws, crowbars) seems alright.
