Hmm -- I'm no longer in PA (

) but my impression of our school and district was that they were strictly adhering to the law but didn't want to do anything beyond that. I doubt I'd have gotten very far with them before school started and they'd had a chance to see my kids. Not to dissuade you but I wouldn't be too optimistic . . .
If you know the GT teacher at your school, you might try him/her first to see how it might be best to proceed. We found that we got great ideas from out GT teacher about how to approach the school/district once we'd made contact.
