If you use a translator property, you can change it from within lilypond
with
\property Staff.tabString = #3
and in the engraver you can read the property with
SCM tab_string = get_property("tabString");
int tab_string_i = scm2int(tab_string);

You add the engraver from withing a paper-translator.
If you wan't to replace the Note_heads_engraver with i.e.
Tab_heads_engraver, you simply say
\paper {
\translator {
\StaffContext
\remove "Note_heads_engraver"
\consists "Tab_heads_engraver"
}
}
Check out ly/engraver-init.ly
to see the definitions of all the default translators.
