I don't really see any difference, unTransform only additionally removes
strech (which unShear doesn't). That means you have to scale the Aabb
(don't forget Facets).

You have untransform sphere shape itself anyway, which gives ellipsoid,
in which case the Aabb is enlarged in the shear direction.

I am very sure that what you propose doesn't work, but you can try to
convince me :-)
