I think I finally see what you mean. You want to add another layer to the
hierarchy, and to force the invertible classes to derive from it. I did not
understand that earlier.

What this means to me is that the current GetInverse API and my virtual
GetInverse would have to be moved from itk::Transform into the
itk::InvertibleTransform. Sounds good to me, and not invasive either.
