Just a thought here, perhaps:
- The header in gabc define the structure of the gabc file (i.e., how
many nabc lines are defined in the file). This means no additional
nabc-related headers in gabc.
- All other configuration (fonts and nabc position relative to the
staff) is in TeX, something like \gresetnabcline{1}{above}.
- You should be able to to disable typesetting of some or all of the
nabc lines from TeX, maybe \gresetnabc{disabled} for all and
\gresetnabcline{1}{hidden} for individual lines.
Bad idea?
