Any issues having stacked stone wall behind speakers

[Grasshopper]

Greetings. I am in the process of finalizing plans for finishing our basement.

With the "look" we have in mind, we want to have the wall behind the speakers (home theater and 2 channel system) be a stacked stone wall similar to this:

My speakers will be out into the room 2' from the back wall.

Part of me thinks the stone wall may actually help with diffusion.

Will something like this sound good, or are there significant issues that I am not thinking about?

I'd love your feedback- (for what it's worth, I don't want to have a heavily "treated" room at least in terms of the look. My space will be a wide-open 1,000 sf room, so it isn't a dedicated theater/audio room).
