cross bracing between joists will block PVC pipe from 96% furnace

The space between a pair of my floor joists will be needed for the intake/exhaust PVC pipes for my new 96% furnace. The existing cross bracing will have to be lost. What can I retrofit to keep the joists stable? I was thinking of putting in tightly fitting 1X4 hardwood slats directly under the floor from joist to joist and then another slat bridging the bottom of the joists once the pipes are in.

Or is there a better way?
