Jeff and I are currently working on stuff closely related to this:
we're presenting on the morphophonology/morphosyntax interface stuff
again at CLS and would like to get some implementation ready.  We're
primarily concentrating on how one could go from a database of stems
(with additional information associated with each stem concerning to
morphotactics and morphologically-conditioned phonological rules) to
(in the first instance) the lexc and xfst files required to build
an xfst morphological analyzer.  Ideally, we'd want the morphophonological
database and the morphosyntactic database (= current LKB lexical
DB) to be one entity, with the possibility of many-to-many mappings
between morphophonological stems and morphosyntactic lexical entries.
