Why not just 1 or 2 Bosch style relays switched on from the M2 to power all the accessories?

If I did my power consumption calculations correctly, I should have enough power to run all of my components through the M2. But looking at my wiring diagram again, I realized that the HD Radio doesn't need regulated 12V, so I can just plug that right into my battery. Also, the only USB devices I'll be using are a GPS receiver, wireless keyboard, and USB for the touchscreen, so I guess I won't really need a hub anyway.
So crossing out the HD Radio and USB hub, I shouldn't need another power supply for the Lilliput and DVD drive, right?
