That's how I started out modding my Mark III. The III hammer will still work fine. Some people add a small thin washer to fill in the hammer's inset, but it's not necessary. If you use a washer, you have to be sure the notch on the bottom of the hammer is not obstructed.
Later I upgraded, and got the VQ Mark II accurizing kit with the stainless trigger. It includes a Mark II hammer.
The Mark III kit is only for someone wanting to keep the mag safety, which I can't imagine.
