I'm guessing you mean going from an external headset, to an internal one. Thus losing the bottom race, and shortening the effective axle to crown by 6mm or so. This will steepen the frames angles by roughly 0.25deg.
The problemn is. In order to use an integrated headset. You need the bearing races to be included in the headtube. If your headtube is designed for external bearings. It wont have this. There are umpteen million types of headset out there. SO maybe I'm wrong. But it doesnt sound doable to me.
