Because spring rate and damping rate are dependent...and since the bitubo kit has fixed damping, there's really no point in changing the spring rate.
That kit is going to work (...well, one hopes) for the designed rider weight (~180-200 pounds), but outside that range its probably not worth spending the dosh.

I'm not exactly sure what you're trying to say, but:
A. Having a suspension shop rework your forks will not cost $2000. Porbably more like $200, and they will be "exactly tuned to you", and will perform nearly as well as anything else for the vast majority of riders.
B. Buying full cartridge internals and having them reworked will not cost $2000. Probably more like $500-600. Potentially the best option for "exactly tuned to you" if you're tiny or huge, but not worth it if you're in the bell curve of rider weights--the bitubo kit is likely the best choice.
C. A swap to any of the various modern MX forks that will slide into the GS's triple clamps will not cost $2000. "Exactly tuned to you" plus more travel, with fairly minor cutomization. Probably $1000 when all is said and done.
D. I don't think you actually meant it, but your statement implies that the bitubo kit is "exactly tuned to you"...which is only the case if you happen to fit the weight range to which they are tuned.
