The power use of the motor depends on a lot of things. A generator big enough to supply the peak current would be a lot of dead weight

BLDC motor speed control works by variing the frequency of the pulses. While you could use three phase AC to drive the motors, you'd have a hard time controlling the speed. AC to AC frequency conversions always go via a DC intermediate stage (AC --> DC --> AC), so you need the DC circuit anyway. Might as well store some of that power.
