Yes, that would work just fine. The fun thing about a composite device
like that is that each of the interfaces appears to the system as an
entirely separate device, each of which can have its own independent driver.
Technically, you don't actually need an interface to use endpoint 0, but
you can't get a driver loaded without one...
