That doesn't even make sense. The answer is no because the question as phrased is nonsensically stupid.
You can't have a brain transplant, as others have said. First, the medical impossibility of it. Even keeping the body alive somehow, how do you reattach everything to the new brain?
Then... what do you do with the old one? Do you stick it in the body of the NT? In that case, you're switching bodies. Who would want my body? Well, maybe someone terminally ill or otherwise truly desperate, I grant you. Or someone who was very optimistic and saw something they really wanted.
But no, I don't hate myself enough to want to die and have someone else replace me. That's a fate worse than death. It's exactly what the curebies want, but I don't think there are any curebies on the spectrum, except maybe Temple Grandin and some crazies.
Seriously, you're asking this question? Do I want to be gone, dead? And then have someone else in my body, trusted by my friends, with free rein to betray them? With the trust I earned, given unknowingly to an unproven stranger? My body doing things I would never tell it to?
That would make a great horror story. Only way for it to be better would be if I were conscious to watch it happen. Actually, I've read those books, the series is called Animorphs.
EDIT: And how come the poll results say 5% have voted yes (are you insane?) but only 94% have voted no? Something's not right here.
