I adore the crossovers by Tarlan on Phoenix. They are wonderful and also the greatest thing because some MB and EC characters have very nice stories and traits which don't suit Chris and Vin. But in our imagination we can create parallel world where Chris and Vin are together again but in the bodies of other persons. And few MB and EC movies seem made for each other.
Here is my list of the wild imagination:

The Rock / Now and Again – what if Commander Anderson didn't die in that shower room and Dr. Morris, who knows everything about human's body, saved his life? And asked him to train Mr. Wiseman?

Dragon Squad / CHAOS – what if Petros didn't die (again, yeah, this is a big issue with the MB characters) in that storeroom? He should be very interesting for CIA and ODS. Or maybe he would find the new master and that master will capture the very nosy agent Dorset and…

From Darkness / American Me – what if the boy from Juvie Hall didn't die (oh, the variety this time) from the throat cut? And FBI agent interrogates him? And then this agent can take the boy out on bail.

The new one:
In a Shallow Grave / American Horror Story – what if Hugo-ghost moves in time and place in Garnet's home? I know ghosts can't leave their homes but in AHS ghosts are very unusual. Daventry was more an illusion than a real person so if Garnet will see Hugo in his house it will be a normal thing for him.

Taken could make the great crossover too: with The Rock if we forgot about time issue (John crashed in modern days and Commander Anderson is alive and lives away from people) and with In a Shallow Grave if we forgot about distance issue. In both cases, John could heal his host.
