yes you could use many different PIC or mess around a timer interrupt routine.
Depending of the wanted frequency it could work pretty well. If you're using the hardware PWM, YES you can do something else as the PWM run in background.
A timer interrupt will be a bit more tricky to implement, but doable for sure.
a 16F628, 16F88 are nice for that. for 2 or more PWM output (2 ccp module), you probably have to jump to a 28 pin device like 16F876 or many 18F.
The Bruce example is pretty nice, you just need 1 PWM and few channel, then you sample one channel by one.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
