Older daughter, suspected to have Asperger's, who is in college now went through the G&T program in elementary and middle schools. She took honors classes in certain areas in high school.
The programs were beneficial to her.
She had contact with good teachers, other kids working at her ability level, and that is where most of her friendships came from.
My aspie son is in the G&T program in elementary school. It is something he really looks forward to. I think he's doing ok there, but the current teacher is not as supportive as my daughter's was. My son is content, and that is the most important part.
Other older daughter, NT, took honors classes in High School. She didn't always do as well, but finally started making the effort and did well in her senior year.
I suspect that kids, as individuals, may or may not want the G&T stuff, or the honors stuff. It can bring some more complications with it.
Got nothing to lose by trying?
