Piggy backing fets has been done by many. Link shows XP-3A as an example.

Pic is one I did for Genius CP around 2012 2014. Most recently did a MX-3A.

I believe this feature of the MX-3A ESC is unknown to most. This esc in its stock form is programmed to accept pwm input of 1kHz, 2kHz, 4kHz and 8kHz with a simple modification. Simply add R1 and R2 resistors (form a voltage divider), value is 1K, size is 0402. This size resistor is "small" but can be done with most ordinary iron with a sharp tip. I have soldered many components this size with a dirty old 40W Weller soldering iron.
Hint, find any copper rod, rivet or similar of correct diameter to fit your iron and sharpen to a point, round point ever so slightly. Clean and tin as it heats up.
Cheers
