Things you might want to consider:

The fork - are you using a full length fork or a shortened one? Full length takes more travel, but is easier on the leg.
hydraulic volume - so, after you know the slave has the travel to move the fork to disengage the clutch, what is the size of the bore and stroke? This is the volume of the cylinder.
Master cylinder - the volume here will match what is in the slave. So if they are the same bore, the travel is the same. This means the effort at the master cylinder is the same as at the slave. So, if you use a smaller bore the stroke is longer.
Pedal lever point - the pedal is a lever - the fulcrum the rod it swings on. A push rod close to the fulcrum has less travel but should be easier to push.

These might help you tune your system.

Good luck
