upgrade master brake cylinder

Just use the 15/16" bore cylinder and ditch the brake booster. With a 15/16" master the pedal feel is great and the effort required isn't that bad at all. It's a personal preference, but I like manual disk brakes on these cars over power disks with a booster.
I really want to do that, but I wouldn't want it to get hard for a road car.
to make this change, how to fix the cylinder master and also the actuation?
