Replacing M8 camera with M8 Eye camera

Greetings! I am on a quest (makes it sound epic) to replace my M8's 4MP camera sensor with a 13MP sensor from an M8 Eye. However, I am having trouble finding an M8 Eye camera sensor for sale. So my questions are: where can I find an M8 Eye camera sensor for sale (can't find them on eBay or general google search)? What files need to be replaced in my lib folder after the switch? And where can I aquire the correct lib files?

Thank you for your time. :)
