On the front brake make sure all washers except the concave ("toe-in/out") one are outboard of the arm and your centering adjustment setscrews are backed all the way out. I get nearly 28mm of space between the pads that way which should have no trouble accepting the ~25.4mm brake track width of the FCs, particularly with cork pads in there which tend to be 1mm or more thinner than the standard pads on the setup I measured. Improvements to the system still in development stage, so won't be seen on any bikes currently in shops.
On the rear brake, same suggestion on washers. 1st generation brakes achieve a pad width of ~29mm this way and the 2nd gen get up over 30mm. Again, with standard pads...corks will go wider still.
