Quadro and GTX 1080 in one system

Hello,
I have a project in which a unity based "game" needs to be outputted to a multi projector screen.
The thing is that we would like to use use projectors without edge blending capabilities.
So the edge blending must be done by software, but from what I've read the Nvidia mosaic feature is only supported by Quadro cards. So my question is.
If I put 2 cards in the system, lets say a gtx 1080 and a quadro p400, can Quadro act as only an output device which provide me with edge blending and mosaic technology, and 1080 will be used to handle the unity project?
I have googled a lot and still did not find the definitive answer. From what I know there is some software which can handle such a task but it only works with windows 7, and it is quite pricy.

If the dual gpu is not an option, can I say build a second system which will act as a monitor for the main machine and do the blending? Maybe it can be done with a virtual machine?
