Wouldn't it be better to fix ttf2subf rather than add more utils to fix
problems with existing ones?

I showed how to do it in a limbo prog I posted here a few months ago.
You map subfonts to standard unicode ranges as defined by unicode.org.
A simple scan determines which pages are present, you then produce subfonts
with 0 width glyphs for
those in a range that do not exist in the source font - causing draw to
render a peterface.
(there are other obvious optimisations to minimise the amount of glyph data
per subfont).

I haven't looked at ttf2subf but the Limbo prog was very simple, it cannot
possibly be that difficult.
Alternatively you could always use my Limbo app.
