The way you drive the FETs might be problematic.

Will they tolerate the power dissipation of being "halfway on and halfway
off" ?

Typically FETs are either "on" or "off" to minimize losses. And that
involves PWM with minimum on and off periods.

I've built similar systems without a microcontroller that did hardware PWM
using a feedback loop. It is doable but can take some tweaking.
