Attaching an arm as a leg should automatically grab anything off the ground into your active hand.  Or it gives an additional hand slot like the borgs

leg item surgeries should be a thing

At the very least, "object pegleg" could be very fun. You could attach any item that can be an object arm, but all it does is give you a walk speed that is in between one and leg leg walk speed. With a chance of tripping.

(If you attach a gun leg, there could also be a 50% chance the gun fires when you trip)

honestly could be good for makeshift surgery if you really don't have any other options
it'd be nice if you could attach missing limbs while on top of a regular table instead of a full surgical table actually
