My wife and I are in the middle of redoing a 1968 house that was basically all original, so I may have a lot of questions in the coming days. In the house, we have a lovely 1960s wall to wall brick fireplace at the end of the living room and I am curious if this is a possibility:

What I would like to do is put up a stud wall, possibly some insulation, make a new fireplace surround with mantle that is normal size and then drywall the rest of the wall.

Additionally, I would then hang a flatscreen above the fireplace / mantle.

I am curious if this is feasible, because in my estimation I will need to bring the fireplace opening out 2 to 4 inches depending on the stud wall. Would I lay new bricks to extend the opening? Is there another option?

Thank you.

(I want to do the stud wall so that I have something to hang the flat screen from, and also a convenient way to hide multimedia and electrical lines.)
