Is it possible? Yup. Is it a good idea? Well, put it this way. I definitely don't recommend doing any of the following:
I don't know if it's a NO or NC switch but: Find the switch and unplug it. Attempt to start. If that doesn't work then it's a NO switch. Put a jumper wire in the harness and try again
Problem #1: I'm guessing this will at least disable cruise control and possibly other systems as well. You could get around that by leaving the clutch switch hooked up and adding a momentary contact push button in parallel with it. Then it becomes push the clutch in OR push the button to start.
Possible Problem #2: legal ramifications if this little hack is ever found to be the cause of an injury collision.
If you insist on doing this, I would suggest you figure out a way to make the car impossible to start unless it's in neutral like what is done when installing a remote starter on a manual trans vehicle.
As far as lightening the clutch effort, it's probably not gonna happen unless a previous owner put some high performance clutch in it, in which case, the answer is put an OEM spec clutch back in it.
