Can we change the Sugar Cube logo in the navigation bar?

Is it possible to change the cube logo which is present in the navigation bar.

From the chrome developer tools I could see the file is present under "styleguide/assets/img/logo.svg". 

I tried to create the same path inside custom folder and replaced the logo.svg and did quick repair and rebuild. But it doesn't work.

I also tried to replace the original file but that also doesn't work. Can someone help.
