J, If you do manage to get in touch with him, I highly recommend his fanzine sequels to the original series.
They're probably the best fan-written sequel stories out there, and real page turners. With an editorial polish and some added texture and detail, they would make excellent legit tie-in novels.
They are, in correct order:
REUNION
RETRIBUTION
REVELATIONS
DESTINY
DISASTER
DAMNATION
RITUAL
There's a coming attraction page for another one called RESURRECTION but I have no idea if that was ever finished or if it continued past then.
