Roxul behind durock behind tile

I have an interior bath tub surround tile project.
The original plan was studs, 1/2" durock, thinset mortar, tile and grout.

Further research convinced me of a waterproofing membrane over the durock.

Then, I was sold on the sound buffering properties of roxul safe n sound.

Now I want to put roxul in the tub surround walls as well.

Is the above combo acceptable? I'm worried about any water penetration through the membrane and durock being able to breathe in the wall.

So can anyone comment on roxul, studs, 1/2 durock, membrane, thinset mortar, tile and grout?

Thank you for your expertise!

That's how exterior walls are done. This is fine.
