Don't see why Kushina's couldn't they're the same jutsu. Yes, they are different but don't know about the outer path part as Nagato, Pein, and Madara are all seen producing outer path rods from their bodies in combat meaning they are linked to whoever is wielding Rinnegan/Sage abilities as Naruto is also shown to produce these. Going back on topic the definitely weren't outer path rods but seemed similar to various sealing techniques previously used on tailed beasted. For example, when Naruto fought Kurama or the sealing technique used to seal Kurama into Kushina.
