Yes.
The novel Draconian Measures contains an appendix with stats for draconians in 3rd edition, written by Steve Miller.
A couple of those were reprinted on the WotC Dragonlance site, back before WotC completely canceled Dragonlance. They might be still floating around there somewhere.
Stats for a couple times of Draconians also appear in the adventure Anvil of Time which originally appeared in Dungeon magazine #86 and was reprinted in the Dragonlance anthology, Best of Tales II.
