Active Noise Cancellation for Roadster
 

I realize that this is late in the game for a model that hasn't even been produced in five years. But is there a way to add Active Noise Cancellation (ANC) to a roadster that already has Bose?
As I understand it, the 370z Coupe got ANC starting in 2016, but the roadster never did. Not sure why--other than the possible reasoning that no one concerned about road noise would ever buy a roadster in the first place
Anyway, more out of curiosity than anything else, does anyone know what would be involved to add Nissan's ANC to the roadster?
