Mixing engines?

[Minimacfox]

Is it possible to mix engines? Like the water in the game is build with Hydroengine & then the graphics is build in Cry Engine 3? And then put it together into a game?

I'm not sure you can directly do this, but you should be able to do it converting some formats or something.
