Forgive my skepticism, but for a child diagnosed with pretty severe behavioral issues, and already accelerated, it seems unlikely to me that addressing the giftedness alone will get the child where he needs to be.
It's lovely to think that these problems can easily be solved by focusing on the child's strengths, but it is frequently the case that a child has both giftedness and something else going on, and that both need to be addressed.
Petunia said her DS is already not taking GT language arts because he can't comply with homework demands. The likelihood is that further acceleration will mean a larger quantity of homework. That doesn't sound like a great solution to me, for Petunia or her DS, at least until the behavior issues are improving. YMMV, of course.
