photon networking and unity networking

hello, i have a question that can we use photon networking and unity networking in parallel in same project? like we want to leave it on user whether he wants to play with unity networking or photon,s one.

thanks

i Think that you can, just by adding the two options before starting any of them, so after the intro ask the player : Photon network of Unity Network, or something like that. but the Photon players wont be able to play with eachother offcourse
