PIC24: Advice on PWM use for BLDC and boost-converter

I have a PIC18F2620 circuit (v2) which drives a 3-phase BLDC motor and incorporates a boost-converter. At low speeds the motor drive is PWMed, and as speed increases there's a transition point where the PWM duty cycle = 100% and the boost-converter turns on. I did all of this manually using 16bit CCP modules and interrupts.

I'm now designing v3 and am looking at using a PIC24. I see there are chips which have 3-phase BLDC drive in mind and so have 6 ch PWM. However for v2 I found...
