Ok, so if I understood you right, Sue can do 1 of 2 things.
1. Shield Johnny, then make a small hole for him to shoot out of
or
2. Contain the vamps in a shield, open a small hole where Johnny can insert his finger and blast them through it.
Both of these scenarios pose some problems though. First, Johnny won't be able to go supernova and channel it all in a finger sized hole, at least not that we've seen in the movies. 2nd, he'd still need to figure out a way to hit the vamps. Not easy to hit speed blitzers in from a finger sized hole. Granted, this nullifies the vamp's attacks, but since they have Alice and Edward they could probably avoid getting caught in the first place.
Another thing to consider is that Sue's shields are not infinite. She's pretty strong with them but has been shown to tire. So if she shields the vamps and the vamps continuously ram into her shield, she'll end up tiring eventually.
