What makes you think the GAI will be significantly higher than the FSIQ, btw? In general, the default is to preference the FSIQ in interpretation, unless there are significant differences among the index scores, in which case one can have a discussion about additional interpretations (although from a technical psychometric standpoint, the FSIQ is still the most robust measure).
If you are looking for documentation of ability measures of 130+, the GAI will not provide that in this case. (If Digit Span and Coding are both at least a 9 or so--i.e., in the Average range--then the FSIQ is not significantly lower than the GAI.) From the scores you've provided, I suspect that the measure that you may find more informative to pursue would be the VECI, which requires two more verbal subtests. But whether it accomplishes your goals depends on your situation.
