Bleh, sorry, been recovering from food poisoning.
Now is this "Unseelie Fey Draconic Lesser Aasimar with LA +1, meaning I have seven levels" or "Unseelie Fey Draconic Lesser Aasimar with LA +2 bought off to LA +1 at level 6, meaning I have six levels"? I'm guessing the latter, in which case yes.
On a vaguely related note, I skimmed my own character creation guidelines and thought I royally botched the buyoff thing (to the point where it would have been a straight equivalency without the actual buyoff part), but no, apparently I was perfectly sane when writing it. 's all good.
