GAI--this probably won't add any information, and likely won't raise the global measure, as FRI is heavily weighted in the GAI (2/5 of the contribution), and that's one of her weakest areas.
SBV--this test has motor tasks too. Also, VSI was among the highest areas. I don't know that moving to a motor reduced test (even if the SBV were that much less motor-involved) would necessarily provide a more comprehensive picture of her abilities. Though it is true that the Stanford has no processing speed cluster. The most likely reason for getting an SBV done at this point would be for access reasons. I don't think you'll get a lot of additional information.
Matrix Reasoning--not really, other than the ordinary activities that are part of healthy childhood. You are correct, though, that weakness in this area is not an unusual finding in individuals on the autistic spectrum.
