Larry DiTellio would be one choice, an SF-inclined veteran of NYPD Blue or similar would be another.
But there has to be a script editor/line producer who's in a position to say "Joe, this is rubbish, rewrite it. or we don't make it."
NOooooo!!! NOT Larry DiTillio! Remember him? Architect of such gems as 'TKO', 'Eyes' and 'GROPOS'? At least you need somebody someplace close to JMS' level and it ain't DiTillio.
Peter David might work. Harlan definitely. Neil Gaiman, since we're dreaming anyway.
