I'd like to see Aruba switch stack be reported in both NPM as a switch stack (it is) and also for NCM to inventory the serials for each of the stack switches.
This should be incredibly easy to put together
sh stacking detail on an aruba gives topolgy, status, serial name, software version, memory status, etc - so this should be incredibly simple for NCM.
This does inventory everything needed, just off two commands.
