Anybody know of an adjustable brake-pedal?

[The Veg]

I've installed lowered-pegs on my GS, which are almost 1.5" lower than stock. I've adjusted the brake pedal as far down as it will go, but I'd like a little more. Not really a problem most of the time, but if I stand on the pegs the pedal is difficult to get a toe onto. Does anybody know of a bolt-on solution to this, or am I going to have to permanently modify the pedal?
