Your idea make sense, I think in something similar, but not with their trim but a way to turn the BIC section externally.
CH bases are a bit "flimsy", what I think help their pot's last long, but for fit HALL is PITA, even the weight of your hand over the base flex then and then the magnets off center.
Other detail is that CH pot axis is part of gimbal, if remove then the gimbal fall apart.
The pot axis has the tip diameter reduced a bit in lathe to allow Bic tube fit tight, so for "tuning" the Bic section can be turned slight. Ideally is if this can be done externally.
Plan eventually replace this with TLE501x.
Interesting your POV HAT solution in Logitech grip.

Bi-Tech 6127 HALL - nice sensor but bloody expensive
Yes, but one cost less than two CH pot sold as replacement.
In HOTAS Cougar "King of the Hill" times people used pay more than 100$ in similar Midori HALL Sensor - even today some continue to pay.
