jaydee,
Earlier this summer I did install a larger master cylinder which did increase slave cylinder extension. Moved from a 3/4" bore to a 1" bore, but the increase in pedal pressure was unacceptable.
I returned to the 3/4" master cylinder, moved some of the mechanicals around and eventually did get more clutch fork travel. But the means to achieve the end wasn't some of my best work. I expected it may not be the answer to long term reliability, so I'll give the HTOB a shot. 
I'm still interested in more feedback!
Thank you,

Not sure what master cylinders you are using but there is a 7/8 inch Tilton MC that I settled on with my ERA. The pedal throw was too long with a 3/4 inch. At first I thought the 7/8 inch was a little too heavy but after putting some miles on it, it feels about right. When adjusting the clutch the slave cylinder needs to be bottomed out and the rod adjusted to where it's pushing the TO bearing just shy of contact with the clutch fingers. That way you gain full advantage of the slave cylinder travel. A fork return spring is usually used to keep the TO bearing from riding on the clutch fingers. But it's important to check regularly because as a clutch disc wears, the fingers will retreat towards the rear of the car as the pressure plate compensates, using up this small amount of free play.
Sounds like you have your mind made up to go to a hydraulic throw out bearing. They sound good in principal - lighter pedal pressure and so forth - but if one goes bad with a hydraulic leak what a pain in the butt.
