I think you have to look at the additional power up front. As you ratchet the front end down with more power your weight is transferred forward. The bigger caliper on the front will make the rear be lighter faster. With less sprung and unsprung weight on the rear the odds of locking the rear wheel will increase anyhow when the coefficient of friction is reduced due to less contact on the roadway.
Additionally the rake of our bikes prevent a stoppie so the weight of the bike is transferred from the rear forward in the form of momentum. With the stronger caliper it could be possible to stop the front wheel from spinning. That could be a really bad thing.
I guess I am just saying to please be careful when messing with the physical principles of braking. The engineers did the brakes as a total package for the weight, sprung and unsprung, momentum, rake, and tire configuration.
I am also thinking that a braided line would be a must on this caliper like in one of the pics.
Now you have my SWAG method of looking at it.
