Ha, I am
familiar with this problem. Launch lugs can be a pain in the butt.
Where is the CG, anyway? I'm guessing somewhere around the cannons. Since your existing lug housing (which is beautiful BTW) is centered at the bottom, your front lug could go between the cannons on the bottom, and could probably be made to blend in with the design reasonably well. Based on the discussion above I wonder if you're actually talking about putting the front lug way far forward, but I'm not sure why you would need to.
If you were starting from scratch, you could conceivably have found a location for the front lug in some strategic place in and amongst the cannons, but then the rear lug would have to be somewhere other than where it is now.
