Cross-overs you know will not happen but wish they would

[automatron]

Have any of you had an idea for a great cross-over game that would be sweet but know would never happen? Well post your ideas here and let's have fun with it.
For mine I had an idea of a Left 4 Dead game where instead of being the usual characters you could be the mercenaries from Team Fortress 2. I could imagine the pyro being super helpful in this game since he would be a walking Molotov and the heavy would be good at clearing out the horde and killing tanks.

Poor spy and sniper though, they'd be useless.

A good one would be and MMORPG mixed with a hack-n-slash, like bayonetta or DMC4,to make each battle exciting and fresh
Unfortunately though, engines and internet aren't good enough to make this, yet

Sniper would be good at taking out special zombies like Hunter and Smokers while they are on building tops and I would have it so the spy can diguise himself as a common infected so he can back-stab the special zombies that are hard to kill like witches and tanks.

Civilization mixed with Pokemon.

...I'm still thinking of how it would fit together but it would be great.

Umm True Blood does have real vampires. Heck the main villain vampire ripped out a guys spine Mortal Kombat style on live television. Plus its pretty graphic and sexed up. So much its almost the polar opposite of Twilight.

Yeah...that's why I said the REAL vampires would kick sparkly arse. I don't recall Sparkles being in True Blood.
