Matching free speed exactly isn't nearly as important as is made out to be on Chief, and the motors are designed to be 1:1 drop in replacements for each other without any adjustment in gearing to compensate. The main thing to avoid is one motor forcing the other one to drive faster than its free speed, which doesn't happen (under load, things even out with these motors nicely). Totally fine to do this.
