I don't (yet) know, but I'd be surprised if this could not be done.
Emacs already creates glyphs dynamically for tofus, and already uses
black-and-white bitmaps at least in fringes.

The proposal is not to change anything to the way Emacs uses fonts, but to
change something to the way Emacs behaves when it does not find an
appropriate font to display a character. In that case Emacs would display
a "degraded" glyph (from Unifont), and would issue a warning that the user
should install another font.

Yes, DejaVu Sans covers Hebrew (100% coverage).
