There is no need to disengage the upper modes in an L2 to fly a non-precision approach.
You can do this in a 4-axis configuration using APP/LOC-IAS-VS with ALT Acquire set. You can fly it down to the runway with this setup, of course you have to be visual after MAPt to be legal. If you need to go around, just press the button on the collective and the lady flies away nice and easy..
A fairly low intensity workload setting if you ask me.
