According to this ballpark calculation, it would take the same energy for a helicopter to fly on the Everest (with ultrafast rotors, which they don’t have) as in water (ultraslow rotors). Since the lack of helicopters in high mountains (>5000m) is a longstanding issue, it doesn’t look like a good approximation at initial glance.
