Hi Joseph: I think there's a long history before 6LoWPAN existed of not assuming that DAD for a given address is a guarantee for any address built on that same IID.
So I'd go for either assume that you do not need to DAD any address based on your burn-in address (see 6LoWPAN ND 15 section 3.1, second bullet), or DAD them all, which is the normal behavior in this Internet.
