So I have inherited an apartment in the center of Rome, Italy a few years ago.

I'm a fellow software guy myself living in Burien / White Center.

I can see where you are coming from regarding weight bearing but, most weight bearing walls on a standard home are close to center or perpendicular wall intersections making in impractical in some cases. 

I've seen designs for a soundproof wall where top and bottom plates are 2x6 and you put 2x4s on alternating edges every 8 inches (16" on center for each side).
