How hard would it be to make a Gregg adaption?

I've been thinking much lately about adapting Gregg to the Dutch language. It's been said that it would be relatively easy to adapt Gregg to any language.

But to be honest; to me it looks like it'd be a very time consuming task and that it would be very hard to take full advantage of the system. Or am I just wrong?
