DOSBox does something like this already.  I lack ideas about to what 
extent DOSBox could be integrated, but at least its CPU emulator could do.  
Or maybe DOSBox could even be bridged/integrated and do all the DOS stuff 
here?

Then IIRC there were discussions in the past about integrating Qemu into 
Wine.  Some folks at Darwine have achieved this to some degree: [1]

That probably won't fly directly [2] but some aspects of the design of an 
emulator integration can be investigated already, IMHO.
