STM32F303 good for 12 independant PWM output signals !

Hello,
for a new CANopen project we planned to use the ARM-controller STM32F303RET6,
because we use it yet in an existing design.
In the new project we need 12 independant PWM-output signals with an resolution
of 16 bits to control 12 magnet valves. This controller has the timers TIM2, 3 and 4.
Each of this timers has 4 independant channels for PWM output.
So, is it possible to use this 3 timers with their 4 channels to generate 12 independant
PWM-output signals to control 12 magnet valves ? The second thing is, that we need to
convert the 12 currents from the magnet valves with the ADC with at least 10 bits.
But I think this is no problem with this controller.
If it is not possible with this ARM-controller, can you give me a solution with an other
ARM-controller from ST ? And if it is possible, can you give me a software sample for
using the timers for my problem ? For a contemporary answer I would be very thankful.
Thanks a lot, Reiner
