I recognize that truck in your pic. It's a one of a kind custom. There isn't any truck, or vehicle outside of RR as far as I know, that comes with the starlight headliner from the factory. I imagine it's going to be rather expensive to have it done custom as well. You'd have to put in each of those fiber optic lights by hand, then put in a control system, although it can probably be done with a cheap remote.
Replacing the headliner in alcantara wouldn't look right in my opinion. Probably expensive, but not as bad as the star light.
I would think wrapping the A-pillar is a lot more practical. Alcantara seems a little odd being that the dash is mostly plastic. Carbon fiber seems a lot more popular for this sort of thing. Personally, if you want to spend money on the interior, there are lots CF parts you can get aftermarket, that will draw your attention away from the A-pillars.
