One generally available resource, very interesting but very limited, is
Michel Antelme's article ‘Inventaire provisoire des
charactères et divers siɡnes des écritures khmères pré-modernes
et modernes employés pour la notation du khmer, du siaois et du
pāli’ - http://aefek.free.fr/iso_album/antelme_bis.pdf

We may need a new control sequence or character for the old writing of
what he transliterates as _kantora_, a word for 'mouse'.  (We
definitely need a few more graphical characters.)

From p20, it would seems that a key boundary may be the abandonment of
subscript consonants for CVC clusters.
