That's quite interesting anon. I think I agree that Astaroth may be able to help you conjure/give authority over Sitri. Satanakia seems pretty unlikely though.
On a semi-related note, have you read the Goetic Liturgy by Jake Stratton-Kent? He does something very similar where he uses Isis or Hekate to conjure Astaroth, with similar god attributions for Beelzebuth and Lucifer. Could give you more context to work with, as well as a way to de-Christianize your practice if that's something you'd be interested in.

I rather agree. It would be strange to try to convince a goddess to be your familiar.
