Widen lats for narrow ribcage

[Spirit33]

I have a very narrow ribcage.We know that ribcage ,it's bone and it cannot be enlarged through lift. I wonder if it is possible to add some lat width (through pulling up or something like this) to fake a wider ribcage /torso when wearing clothes.
I see many pro dude lat can only be seen a little under the armpit from the front.
I'm newman to the gym , I like pull-ups and I will keep doing this, I just wonder if add some lats width will help my narrow ribcage.
