If it's a hydraulic clutch, wouldn't some alteration of the ratio between the master and slave cylinder bores provide some assistance at the pedal, or effectively reduce the load required to push the slave piston out?

What vehicle? Might be worth checking everything is in good order first off as not many clutches are that heavy by OEM design, but a worn/damaged actuating mechanisms can cause problems as can a clutch that is simply nearly worn out.
Also possible that the wrong master/slave cylinder has been fitted at some point affecting the hydraulic ratio? Some reduction of effort is possible by using either a smaller diameter master or a larger diameter slave though you can't usually go all that far with this before you end up with too little travel for the clutch to fully disengage.
Finally, it is perfectly possible to use a remote servo as used on the braking systems of some older vehicles.

I'm going to use a cover plate which has Avery high clamp load, changing lever ratios won't do it, thanks for input!

My good friend and car colleague has fitted a small servo unit to hydraulic clutch setups on several of his cars over the years. He does it to make it easier for his gammy knee, but any of the cars I have tried the clutch is a joy to use compared to any others  |
