Yes, you'll feel a difference if you change any fork parameters, but you'll also tend to find a way to compensate, if the new fork is anywhere in the neighborhood of the old fork's spec.

That being said, I couldn't find much info on your fork, but I saw some for the 60mm version. ATC is listed as 470, which is right near the ATC of most 80mm 29r forks. If you want a fork with similar ATC and all of the touring bells-n-whistles, check out the Surly Ogre fork:
