I doubt it, unless either compnay makes a caliper swap specifically for the FSVT which allows you to run stock rotors. Usually the aftermarket kit have a different rotor offset thus requiring you to run their own rotors with their calipers.
Why do you need different calipers anyway, except for bling?
IMHO the FSVT brakes are excellent and with better pads I'm sure I can hold my own with the BAER kits.
