Could somebody give me more information on what it would take to swap out the brake booster for Manual Brakes, or have an adapter plate? I don't quite get it.
You've got two options.

1) Find a master cylinder with a smaller piston bore. That'll give you more line pressure with less pedal effort. I suggest racing supply sources to find something like this. Summit racing shows as small as 3/4".

Wilwood 260-1304 - Wilwood Aluminum Master Cylinders - summitracing.com

2) Move the pedal pivot point down, closer to the master cylinder. Thus, giving the pedal more leverage on the cylinder piston.
