Ed, I once had the opposite problem, that of not having quite more than 3” of pedal travel and thought that was way too little. My DD had more.
I ended up messing with the pushrod stroke on the brake pedal (even though every service manual I had said “don’t mess with this!”) by pulling the pushrod back a turn or two and gaining a bit of added stroke that way. You might do the opposite by extending the pedal pushrod (turning it in), say, 1/2 turn at a time til it brings your pedal up a bit higher.
Of course, there is this thing about the optimal gap between the pushrod and the piston when the pedal is released. If the pushrod is too far in it can make your brakes drag all the time - Not good, so there is that to consider, but if you currently get a hard pedal, rather than a squashy one, but it has a lot of travel before it hits bottom, this might be something to consider. Worked for me. In my case it wasn’t air that needed bleeding, it was just a Mechanical mis-adjustment.
