This is what I would do...
However, I would use inside spin with a stop shot, slightly cutting the 4 hard enough to just come a little back off the side rail.
The inside will put reverse on the four and sharpen the angle a bit to hold the CB behind the seven.

Play safe, push the 4 to the side rail hard enought to hit and try to leave the CB stuck on the 7.
