reason for no response is nature of your request. which is uncommon for a headlamp. your specified form factor can be done, but not sure why you want this config.
please consider Stenlight which is designed to accept an external pack. it's easily modded to accept SSC P4.
for high powered headlamp applications, do a search for biking headlamps. I've got two HID headlamps powered by external packs. ARC HID and Niterider HID storm. bad news is they are $400 range ea
do a google search and you'll find all sorts of info
almost forgot... seems streamlight, eveready or someone makes a cheap head lamp driven by a 4D belt pack. that might be the cheapest way to find a suitable host for your mod. seems reflector was aprox. 2in, still quite large. uses an incand bulb. stock.

I appreciate your response. The reason I didn't jump at the original Petzel Zoom suggestion is that it appears to have a reflector much smaller than 3" and it also appears to have a conical reflector rather than parabolic. And since I was really looking for a "Custom" headlamp rather than a retrofitted off-the-shelf headlamp that didn't appear (at first glance) to have the potential for what I wanted, the suggestion didn't ring my chimes.
Your business approach is also alien to me. It has been my experience with over 40 years of ordering items/products specially made to my specifications that the sources interested in the project usually inquires with additional questions needed to clarify my needs, and then THEY propose a price. Sometimes I accept the initial price quote because I recognize that it is a fair or better price for what I am getting - an excellent current example of this is the recent purchase of the above mentioned ElectroLumine P4 Longthrow flashlight - other times I renegotiate the requirements/price before agreeing. Your approach indicates that you are not really interested in the project per se, but would be interested in getting some money if I offer enough. NOT a good justification for pursuing this business approach. I'm not interested in making a financial offer. I say what I want, you say what you want to do it. If it is fair or better, we agree and proceed from there.
