Thoughts on line lock install

[just plain john]

If one wanted to install a line lock AFTER the combination valve, one port from the valve that used to go to a brake is plugged. The remaining port is then routed through the line lock. After the line lock, it is supposed to T with each end of the T now going to each front brake. My question is this: Will the diameter of one front brake line (the one coming into the T) flow sufficient volume to operate what formally used two lines before? Would pedal effort change? Longer/shorter pedal stroke? Seems like there's a trade off somewhere.

I didn't notice a difference, and I have 12" brakes on my car.
