HC-110 is a very different developer formula and you will not find a
dilution that is "equivalent to" D-76, though perhaps you may find one
that gives similar times and temperatures.
One problem you won't easily overcome with HC-110 is that it reduces
the native speed of the film somewhat, so if you want to be able to
have the choice of developing your film in D-76 or HC-110 depending on
availability, you will have to down-rate its speed and accept some
amount of additional density when developing in D-76.
On the other hand, it also keeps pretty much forever. Even after it
starts to change color its properties as a developer take a very, very
long time to degrade. I bet the bottle the original poster is worried
about is actually okay.
