You'd get at least the same amount of sound attenuation
by just sheetrocking inside and outside the studs. Fill
in the cavities between the studs with fiberglass and
you'll get a bit more high frequency attenuation.
Layering sheetrock in the spaces between the studs will
be a lot of work especially with 5/8" firerock. That
stuff is heavy.
Putting two layers on the outside would probably even
be better than trying to fill cavities with sheet rock.
It ought to stiffen up the wall a bit more.
Good Luck,
