Yeah Al, that's a great suggestion. I was looking at the AH1815 last night.
The challenge is getting the whole assembly as thin as the original, which
presents a not insignificant challenge-
Even using the SOT553 package of this:

trickery, like have it mount into a hole into the center of the board.

Since it isn't very fancy, I wonder if you could make a new board with a
modern Hall
