I’m wondering if converting to a hydraulic clutch would help you.
I don't recall what vehicle I was working on years ago, but it had a hydraulic clutch. The thing which amazed me was that it had a really strong pedal return spring. I am assuming that its design was to simulate the feel of a mechanical clutch.
With the spring removed, you could operate the clutch with your pinky toe. (Well, maybe a bit more than a pinky toe, but you get the idea.)
The question is, can a much weaker pedal return spring be utilized and still have the clutch function properly?
