Imperious Bloodline valid option for Blood Arcanist?

[Analysis]

Perhaps this is nitpicking, but curious on how it's being called: the Blood Arcanist arcanist archetype lets you choose one bloodline from those "offered through the sorcerer bloodline class feature". But for bloodlines like Imperious that are not available to every sorcerer, is this condition still fulfilled, even for a human arcanist? The reason I am unsure is because the bloodline "is available for human sorcerers" but thus not for just any sorcerer, and the arcanist is not a human sorcerer. Can a human Blood Arcanist choose Imperious for her bloodline (or analogously for the Kobold bloodline, etc.)?

[Kazaan]

Even if it isn't available to all sorcerers due to racial restrictions, Imperious is still "offered through the sorcerer bloodline class feature" so it would still qualify. What it's trying to differentiate are bloodlines offered through classes like Bloodrager. Bloodrager's bloodlines offer different powers compared to Sorcerer bloodlines to account for Bloodragers being more combat-oriented classes and not full casters. So a Blood Arcanist couldn't pick the Bloodrager's version of the Aberrant bloodline. But the Imperious Sorcerer bloodline is fine, so long as you're either Human or count as such for rules purposes (eg. half-human, native outsider with a "counts as human" feature, etc). You also couldn't pick the Wildblooded versions of the bloodlines because those are offered not through the Sorcerer bloodline feature but, rather, through a Sorcerer archetype.
