Just a poll, would many of you relocate an entire family 1000+ miles for something like this? New jobs, selling the house, new school for the younger child, pets...

My extended family thinks this idea is nuts and we should find a way to make her current high school work b/c we are teaching her to give up / quit when something is hard if she doesn't see it through.

I see that to a point, but we don't have a long history of cutting and running whenever the going gets tough. I've also gotten the insinuation that dd's loneliness is due to her being condescending and/or arrogant. While I will admit that she is ticked at some of the other kids with whom she's had to do some projects and vented about that at home, she's always been really well liked and I don't think that she is unusually full of herself or rude to people (other than immediate family -- she and dh don't get along well).
