Saji could probably obtain 4 Balance Breaker and a fused form like the Vritra Promotion.

And no the Juggernaut Drive is unique to the Boosted Gear and Divine Dividing. For other Sacred Gear with beings in it, they are called Breakdown the Beast and are inferior than the Juggernaut Drive. But Saji doesn't have either of the two since Vritra's conscious was restored by 4 Sacred Gears, so his SG lacks the ability to use that.
