Hi,
I’m just following up to give a quick update.
I stumbled across a project page (Link below)
he was able to achieve exactly what I imagined being able to do with the cheap oem DJI Gimbal/Motors that are cheap & widely available.
**FYI from what I understand, the way these motors & hall sensors differ from the one you mentioned is that these are
(BI-POLAR LINEAR HALL SENSORS (Not Hall Switches) that implement a ratiometric calculation for angle.
I was actually pleasantly surprised when I realized @lurenaud is actually the same guy who replied to my original post on here a while back! 
It appears @lurenaud & I are the only ones in the world who saw the potential of hacking/retrofitting these beautiful stock DJI Micro Gimbals haha!
