Driving a H-Bridge with a PWM ic

Hello.

As usual.... running out of pins.

I have a BTS7960 40A H-bridge as discussed in this thread here:
https://forum.arduino.cc/t/dc-motor-driver-bts7960/606686

I would like to entirely control it over i2c and wonder if a chip like this could achieve that:

Lots of i2c addresses to use on this IC.

Can anyone foresee any timing issues? I am kinda stabbing this together if I am honest.
Will certainly need to breadboard it first
