No you can't. Unless you're sliding sideways too or it's not really solid pavement or you're bouncing, any case you aren't getting more stopping force than 0.6 g. It's IMPOSSIBLE. The coefficient of friction of rubber on concrete is well upwards of 0.7 g. The tangent of the angle between your center of mass and the front contact point is about 0.6 or less. That means when stopping force exceeds 0.6 times mg, then the forward pitching torque of braking exceeds the downward pitching torque of gravity, and you're going flying... It's really quite simple.

It's also really a moot point if your traction happens to be less than that (and on dry pavement it certainly is NOT less than that) because either way... you can't stop with more than 0.6 g. PERIOD. No brake in the world or open minded progress can change that in the geometry of present road bikes.

ANyway, when I'm flying over the handle bars after applying front rim brakes I'm supposed to "try harder?".
