1) Agree, you can't get at various bits of data that must be present in order for the card to be able to do what it does. Most likely sits in private 'files' that READ DATA can't access.
2) Yup, and combined with '1' this means that you'd have to get the banks to do it
3) You'd have to get some more cross-scheme standards about the crypto capabilities sorted out. I estimate we could have all the schemes in agreement by... 2025? Or is that optimistic?
The benefit would only be to the consumer, in the same way that Coin may benefit people, however any method of doing this with EMV would present some sort of extra attack surface and that's generally Bad(TM).
