Braking a stepper motor

I am working on a hobby project where a stepper motor is sometimes driven and sometimes braked. Now I want to ditch the stepper controller and use a 2H bridge to understand the principle better.
The normal control already works perfectly for braking,
I now consider the following: If all coils are short-circuited (i.e. all 4 pins are connected to each other), as is well known, a lot of braking torque is generated.

=> If I now use 4 MOSFETs to step all 4 pins to GND, the effect should be the same, or
drive a switching FET (like a BJT) in only one direction?
