Welcome to the site.
Is it the reach with the finger tips or how hard it is to pull in the levers?
You can fidle with the cable adjustments on the clutch to improve reach and still disengage properly. People tend to go shorty levers on the clutch but I have seen some that are full length but step in to make the finger tip reach possible.
If you are trying to reduce how hard you will probaly have to change the perch as well for a better leverage ratio. That starts costing dollars but there are some nice ones around that fold if you have an off to prevent snapping the lever.
