Just so you realize, you'll likley only have 3, maybe 4 airbourne units in your force, up against an enemy that will blow you out of the sky with any number of high strength shootyness. Plus you won't have anything to take or hold an objective.
This isn't directed at just yourself, but I have a hard time understanding any attempt at an "Air Cav" army at low points. You'll be playing a guard army with 3 mid armour vehicles and 35 or 40 easily slain guardsmen, up against perhaps the shootiest of all opponents.
At least with Chimeras you could afford 5 or 6 "Vets in Transports" units, with some points left over. And smoke launchers to get you there. And Heavy Flamers on the hulls. And then mobile walls to block LOS...
