It's possible to add support to sophisticated backpaks?

sophisticated backpacks should be supported. Any custom JEI integration they have will be forwarded by JEI to EMI if you install both.

Not entirely supported. Only Destination.NONE but no Destination.CURSOR or Destination.INVENTORY. It just fills the crafting slots but doesn't craft, the same as #499.

And, EMI doesn't detect any craftables, though there are actually some items craftable.

Sophisticated backpack's integration is provided by JEI, which doesn't support craft to cursor/inventory or craftables. Sophisticated backpacks would need to add first party integration to support these features.
