A bigger knuckle can't do anything other than making it necessary to 
have an even longer drop screw. Consider the geometry. It's the 
wrong direction for the problem. Heel height and capstan height will 
have no relationship whatsoever to this. None whatsoever. If the 
bore distance is correct (verifiable by measurement), and the action 
spread seems to be usable, a smaller knuckle or an addition in 
thickness to the drop screw pad on the rep lever will get you in the 
ballpark. Consider what's there and the likely result of geometric 
changes.
