Bloodline Development & Primalist (Or other Archetypes)

[Sarzael]

Say, I'm playing an Arcanist. With this Arcanist I take a Bloodrager dip, and then take Bloodline Development to advance my Bloodline.
But I also took the Primalist archetype.

If the arcanist already has a bloodline (or gains one later), taking this exploit instead allows her arcanist levels to stack with the levels of the class that granted her access to the bloodline when determining the powers and abilities of her bloodline.

Where does that leave me? Could I replace a bloodline ability with rage powers?

At 4th level and every 4 levels thereafter, a primalist can choose to take either his bloodline power or two barbarian rage powers.

Alternatively, what about a Crossblooded Sorcerer? Or a Razmiran Priest Sorcerer?

Would the Crossblooded Sorcerer be able to switch bloodline powers around? Would a Razmiran Priest not gain their ninth level ability that replaces the appropiate power?
Would they gain their ninth level bloodline power instead while keeping the changes that the one level of Razmiran they got does give them?

Essentially, how does Bloodline Development interact with archetypes that modify your bloodline?

Uh, bump?
Thought about it a bit: Bloodline Development says that the levels stack with your other CLASS, which makes me believe it does indeed give you any Archetype abilities that would replace the Bloodline. Thoughts?

Arcanist would only power up the bloodline, as far as i can read it. arcanist doesn't let you switch things out, the bloodrager archetype does. Arcanist only advances the bloodline.

Your Arcanist level stacks with your level in another class for the purpose of advancing the Bloodline.
That is, if you're a Crossblooded Sorcerer, it sounds like it'd advance your Bloodline as if you were gaining more levels in Crossblooded Sorcerer. If it merely advanced the Bloodline, which one would it advance? Would you count as having both bloodlines, and thus advance both?
If you were a Razmiran Priest, would you gain the Bloodline's ninth level ability, but keep False Focus instead of Eschew Materials?
What about Tattooed Sorcerer that replaces your first level ability?

I think it's a far more confusing situation than that.
