You could use everything, from DX5 to DX11 because as far as I can see, only basic drawing methods are used. KaM in DX11 sounds nice, but it would bring you exactly 0 advantage to the current system in terms of visual quality, it would look the same and run in the same speed. The game uses none of the newer features.
Only using a different rendering API doesn't change anything on the game unless, of course, you start to work with the specific features the new API provides.
However, the main advantage that I see with DirectX is that Win7 doesn't need to deactivate the Aero theme on game startup then, thus increasing startup by one second.
I think that Krom and Lewin don't want to support two graphic APIs, and since they want to have the remake running under different OS, OpenGL is a must. But I don't think there would be a problem if another coder would work on DirectX-support.
