I requested from Lancair agreement to make this change in
1991. It was rejected without explanation.
Maybe just CYA, or an issue with torsional stiffness of the
rudder, or a change in vertical fin resonant frequency, I don’t know. You are the engineer. Good luck.

A suggestion,
I did this on my 360 on the vertidal
stabilizer. The couterweights were placed on the leading edge of the
rudder and in the counterweight overhang on top of the rudder. The moment
arm on the leadig edge was about 2 inches verses about 6 inches thus you need
only about 1/3rd the weight on the top of the rudder. My solution was to
add 1.5 inches to the height of the rudder and vertical stab. More room
for more lead. overall weight was reduced.
An addditional benefit I received was I increased
the demonstrated cross wind component for landing. I landed in a 24 knot
crosswind at Jackson Hole Wyoming one time.
