Hmm... worldwide petition with a previous announcement within many forums, websites and social media.
We could start by increasing the number of followers within this and prepare valid ideias to present to fujifilm.
Even though this approach failed with pack film, it was something that was already "stopped" in their side.
With instax, something that is still increasing in popularity, what they want is profit, and b&w would help alot, and It's kinda cheaper to make from the info i've gathered.
