That would be my worry. In theory, it should work (lots of pads have one or more grooves) but the pad
may not handle the stress of cutting the groove and/or any extra stress created in use.
Personally, I'd get pads that are designed/manufactured with the groove rather than risk failure from a mod gone wrong. Brakes are pretty high on my No Experimenting List. Better safe than sorry.
