... I was going to suggest to the OP that if anything needs
renewing, fit a fluidmaster conversion.

I did recently and it's the dogs; dumps the tank in about half the time
and
refills - quietly - in well under half the time.

20 ish squid from B&Q

Seeing as how this is much more expensive than replacing like with like, I
thought I'd ask - does anyone know how the longevity compares with a
conventional diaphragm flush?

The flapper-type flush valve itself has practically nothing to it so all
there is to replace would be the big washer. The £20 B&Q kit includes a
Fluidmaster bottom entry float valve which you may or may not want. The
flush valve mechanism makes up for being simple by being a bit heavy to
use - it needs quite a push on the button to operate, unlike the vastly
complicated push-button flush valves you get with newer (especially
continental made) close coupled cisterns where the push button operates with
a feather touch. I'd be inclinded to use the flapper valve with an existing
lever handle and bodg^H^H^H^Hengineer a springy extension to the arm inside
the cistern which the lever operates to get a suitable action to work the
valve - that way you'd get a very light lever action, instead of a very
heavy push button one.

OTOH Grahams do a (forget the make) push button operated valve where the
button mechanism is on a flexible linkage (like bike brake/gear cables, but
plastic) and this (a) does have a light action (b) only costs about £12.
Even adding say £5 for a bottom entry equilibrium float valve that's cheaper
than the inferior (IMO) Fluidmaster kit. It also has two flush volumes (for
'liquids' and 'solids')
