That said, I don't feel strongly about following RAW here, and you're putting forward a decent argument for treating bloodline "levels" as LA. I'm mostly wondering about bloodlines advancing CL. Buying off levels that still count for casting seems like it could lead to situations like being a higher level caster than the number of actual levels in a caster class, allowing for early qualifications and similar tricks.
