I have a few questions? Are the covers "hot-swappable" or must the device be powier-cycled to use the cover? if there i a standard connection like usb then it could be like a pc where you can attach any number of things and and have it function. And since it is linux OS you could include any driver you needed and integrate it at a low level if necessary. Truly the possibilities are endless as we can see what is done with the iphone and it's accessories. Now if they make the second jolla phone the same size then the accessories can be reused during upgrade. maybe the Jolla 2014 edition (like they do with cars, same model, different year.)
