You're talking big...BIG money here..
Billet fork bottoms from someone like JHP will set you back at least a grand, then you need the calipers and pads, no idea how much the stock brembo radial calipers are, but I can/could get hold of some GP calipers for about £800 second hand, so you'd be looking at over 2k easily for this.
Might be cheaper to just buy a set of 05 999s Ohlins and calipers
