I'd do it.
If the water lines are copper, I'd just sweat new piece onto existing to extend them and then use copper pipe straps to connect them to the stud. I'm sure that PEX is fine but I don't want to connect dissimilar materials behind a wall. That's just me. I agree with using the quarter turn ball valves.
You can get PVC connectors that has a threaded end. I don't know if they're the right size to connect to old steel but I'd bet they are. If not, there are clamps connectors to go from iron to PVC. I think the most difficult thing would be to take off the 90 degree elbow at the top of the drain. I'd imagine you'd need a couple of pretty big pipe wrenches to unscrew it. Or cut it off and use a clamp connector to go from the old to the new PVC.
