That would be me!
Unfortunately I have a 98 model ZX9R so I have no idea how it would relate to the later model ZX6/ZZR600.
The main ($$$ wise) issue with doing it on my ZX9R was the 2005 ZX6 forks were shorter then my 9 forks, hence it required a custom "stepped" top clamp to retain the ride height. If the forks are a similar length you should be able to get away with using the standard top clamp that comes with the new forks which would save a *lot* of time/money.
If you just want the standard forks to work better and they are nice low km units, it would probably be better to spend some cash on getting them rebuilt with better internals. If you have the time/money though I say go for the swap!!. The new forks look shit hot and its sure to get attention wherever it goes.
The radial brakes also crap all over the old 6 pots.

EDIT: Forgot to say check on kawiforums.com they have a massive ZX6 following on there and Im sure someone would have done the swap on your model.
And a pic of mine
