Graham, you have my sympathies! Been there, done that.
I ran my TR3A for several years with a broken taper pin (although in my case
I didn't realize just what the problem was, thought it was because I had
mixed and matched components). My work-around was similar to yours, except
I made a longer pushrod instead of moving the slave cylinder. It didn't
seem to have any bad effect. Eventually, the throw-out bearing failed and I
discovered the broken pin when I got it apart.
The bushings in the transmission housing that carry the shaft might wear
faster, I'd plan on replacing them while you have it apart (when you do get
it apart). They aren't expensive or difficult, and are probably pretty well
worn anyway.
There have been numerous fixes written up for broken taper pins. I chose to
add a cross-bolt on the other side of the fork. See

for some others.
