First of all, you don't sound like an ass at all
Yes, the brake booster will most likely be different between the CCB and steel brake cars. And most likely so will the brake master cylinder on the F8x. On the F1x the CCB and steel brakes use the exact same caliper with 6 pistons, so the volume of brake fluid needed to move 6 pistons is the same both for CCB and steel. On the F8x on the other hand the steel brakes use a 4 piston caliper whereas the CCB has a 6 piston caliper, requiring a master brake master cylinder with a larger displacement.
However, it's not uncommon for aftermarket brake kits to work well with the std brake booster and master cylinder, even though the bite point and friction is different. BMW has to make a brake system that meets a lot of different customer requirements and can be driven by your aunt Mabel without her hitting the windscreen when she brakes...
The issue you might run into is that the brake booster isn't strong enough to give you a positive/reassuring brake pedal feel if you change from CCB to steel jobbies. But that is also down to the brake pad you use, so you could compensate by using high friction brake pads that wears quicker but provides better braking.
Best bet is to buy a kit from a reputable company such as Brembo, AP etc.
