Any out of balance would seriously affect fatigue life, and it would not be long before the rotor parts failed. Any unusual vibration is bad - get the machine down.
In theory removing half the blades, if system is still in balance, doubles the blade pitch. This means machine limits are halfed, so any manouvre will stall the blades with a good chance of overtorque on the transmission. Not generally a good idea.
