I thought of that too, John. It is a solid idea with one exception. The conical insert in the wheels where the studs come through is shaped like an ice cream cone, and it looks like a Y if you were looking at it from the side. These inserts look like to be steel, and not aluminum like the rest of the wheel, and they have been definitely machine pressed into the wheel. They do not appear to be thick enough to endure deepening. Looks like if I would machine it deeper, the top V part meeting the stem, or the I part (I am trying to explain this with letters!!!), would become too thin and would not hold. In fact, just eyeballing it, it looks like it would definitely destroy the wheel's stud holes. I know I am not using the correct terminology for all this, so forgive me for that.
I took some closeup photos and I will post them the first chance I get.
