What if DC had been bought by Marvel; Justice League Dark

I once read that Marvel had once tried to by DC before DC folded into Warner, mainly due to the reluctance of DC to sell Superman and Batman? But, what if? What would have a DC-Marvel merger have looked like?

What would it have done to the Justice League Dark?

The team would have a similar origin, fighting off an insane Enchantress, but there would be some new players in the game, and thus new story arcs. With foes of two different worlds of magic at play, can they contain the force of two different universes worth of magic?

Note, aside for Madam the organizer, the team now has seven members, based off the general starting number of the normal Justice League
