At newsarama, in the remembering Mike Wieringo thread, Mark Waid, besides giving a nice remembrance, and some awesome sketches, mentions a pitch he and 'Ringo had given twice, upon request, to DC, for Aquaman.
It was rejected both times.
However, he has put it up there to be downloaded (and I've posted it below, though if that's a problem, feel free to delete and let people go see it for themselves).
Sounds like it would have been good fun - and it's a shame we'll never get to see it.
Looks like someone else shared Greg Hatchers dream for Aquaman.Originally Posted by Mark Waid
