If Goku goes into this battle with no knowledge of Juggernaut's abilities, then I don't see him making use of Shunkan Idou as he'd be putting too much effort on trying to dent Juggernaut while Juggie shrugs off the damage and being SSJ3, the form will eventually exhaust Goku and he'll be at Cain's mercy. If Goku comes into battle with knowledge of Juggy's abilities, then he would be focused on BFRing Juggy with Shunkan Idou as Goku's ability to fly and his immense speed would allow to create such an opportunity.
