Based on what you’ve described, it would not hurt to set up an appointment with a FA officer. I would not get your hopes up, though, as asking for an additional $17K is a LOT more money than many schools will swing. I have heard that it is very rare for schools to increase an offer by more than $10K - perhaps others can comment on likelihood of an FA appeal granting more than that.
Were you not able to run a NPC at this school?
