Wine doesn't support d3d11 yet, so this is probably better considered an enhancement. (Let's see what Henri thinks!)
I think that for now, a stub dll would be enough. Most games with DX11 support have a DX9 mode that we can test, so I suppose that a stub would make the apps run. However, new engines like Frostbite 2 do not support DX9, so at some point development will have to consider implementing DX11
