I’m wondering if converting to a hydraulic clutch would help you.
A hydraulic conversion MAY help, but lighter pedal force would require a longer stroke.
Jerry's suggestion of a hand linkage would probably be easiest. Although a hip replacement like Martin suggested would require less labor on your part.
Back in school when I took my Model A to an away football game, I was stuck in traffic getting out of the parking lot. By the time I got clear of the traffic, I had "sewing machine" leg trying to operate the clutch, which had a harder pedal than usual.
