I don't see an issue with it, both wires are just 12v supply wires, make sure the wire is fused though. In reality, if it were me, I would do it the same way you are thinking, no need to run a separate feed wire, and putting it on the switch will be fine as well, I actually hated that I didn't have a switch for the lights on my spiderbox, but it will when I'm done with it.
