Hm, so your brakes, through the boostless booster, are working "okay"? That means you can definately just find an MC of a slightly smaller size and replace it. This actualy would have similar results as the folcrum adjustment. There's no hocus pocus in the brake system, it is all simply about "mechanical advantage". In the end, you get the same ratio of piston-to-pedal motion as your piston-to-pedal force. So if the folcrum adjust makes the pedal move too much with not quite enough brake force, then go to a smaller MC and you're set.
You will find that having a booster makes for some "dead movement" in the top of the pedal motion. This is due to the rubber or springy parts in the booster compressing, and the pin moving a little before it hits the pin on the MC. That can be eliminated by bolting up the Honda MC directly. If you get "okay" braking, then you are very close to a successful un-boosted system. No boost = no power loss when braking
btw: Congrats on your first in-town trip. Musta felt great
