It's possible, depending on local circumstances, and what sort of view local panels tend to take. In Bucks, for example, where only VR is tested, appeals have sometimes been known to succeed where a child has been shown to have considerable academic strengths in other areas such as maths. On the other hand, this might be a more difficult sort of case to argue in Kent where not only is there an overall qualifying mark, but a minimum score is required in each of VR, NVR and maths.
The interesting thing about your EP report is that, despite a relative weakness in verbal ability, the overall result - the general IQ - was still very good indeed (the 95th percentile).
Generally speaking, when putting an appeal together, I do feel it's important not to focus on extenuating circumstances to the extent where this overshadows evidence of high ability. As a rule of thumb, extenuating circumstances shouldn't take up more than 50% of a case - probably much less ........
