Dear Oliver,

A few other names come to mind:

Jayantabhatta (who wrote the Nyaya treatise Nyayamanjari as well as the play Agamadambara);
Jnanasrimisra (author of works of kavya as well as pramanasastra);
Possibly Sankara, whose very diverse oeuvre may be difficult to assess owing to
controversies about attribution (though this might make him an interesting
test case for what you are doing).
