Ross from The Brave and the Bold ...The Lost Issues! Created this interesting photoshop cover.
I think they would make an interesting couple. A title with them opening a detective agency in Manhattan would be a total hit. The Grimm & Dibny Detective Agency, Ralph would be the intelectual, Ben would be the tough street guy and Sue their business manager.
To read from its creator go to The Brave and the Bold... The Lost Issues!: The Thing and Elongated Man. There are plenty of other weird team-up covers to enjoy there.
I like his opinion on Ralph and his spot on the Justice League, the character has been doing terrible after the mid 90s.
