Although there were some major problems with both the mechanics and the premise, I always thought Council of Wyrms was an interesting setting. I'd love a chance to run a one-shot [using 3.5 rules in general and the Draconomicon in particular] with the starting adventure from that book...where the adventure begins with the PC dragons hatching.
In that particular setting, dragon PCs would be an interesting option...I'd be tempted to tweak the setting so that half-dragons were not outcasts, but rather a sort of intermediate aristocracy --- below the dragons but above the gnomes, dwarves, and elves. Each dragon clan would include its half-dragon offspring and extended family, and each player would control both a dragon and a half-dragon vassel.
