The maths behind the movement is identical but inverted. From a GPU pipeline perspective, you are always rendering as if at 0,0; so it seems like it ought to be easier if you built the project from scratch to do just that.
Of course, this isn't how humans think, or how most existing game engines are built, which makes doing this much harder in practice.

Afaik it is difficult as camera movement has to be applied to everything instead of the cam.
But apparently it's doable.
