I think a refereed forum -- more likely a conference with proceedings,
at least at first, than a journal -- is an excellent idea. But
don't underestimate the amount of work it would take, on an ongoing
basis. It also takes a long time to establish enough credibility that
academics would publish in it. A better path might be to carve out a
niche in an existing conference or journal.
