Question regarding Victor Sp

[hwu24110]

So as we were finishing the robot and testing it out, we encountered an issue with the Victor 884s for our drive train. Two of them weren't working. I swapped the PWMs for them since we're using tank drive, and now only one works. (At competition, I may be swapping a bunch of PWMs as that had seemed to have worked in the past.)
To be prepared for our competition next month, we might purchase a Victor Sp to replace it, but would it be safe to have one Victor Sp connected to a Cim motor and a Victor 884 connected to another Cim motor, both motors attached to the same gearbox?
