D76 is fine for negative processing.  It was, in fact, originally designed 
for hand-processing 35mm motion picture film.

D76 will get your gamma in the range of 0.6 to 0.7 if you time it right,
which is about where you want to be for a negative.

However, if you want a first developer for reversal processing, you will
want a much more contrasty image heading into the bleach.  D19 will give
you a gamma exceeding 0.9 coming off the first developer.  If you processed
long enough in D-76 to get you enough gamma, you'd be spending all day and
you'd lose detail in the process.

And, of course, time is just as critical as the developer you use.  When
in doubt, shoot a foot or two of a grey scale wedge and hand-process it.
