Line array across a car/truck window?

I’ve seen some home theaters with line arrays from floor to ceiling. How hard would it be to incorporate this across the front window with say 1”-2” drivers? Or even across the back window of a truck?
As far as the R-L stereo channels are concerned let’s just pass on that for now (I’ll cross that bridge later). I was just wondering if this could be done in a car / truck format.
I though this would be a fun next project but first I wanted to see what you all think.... bad idea?

Any links to help get me started or driver recommendations?
