This is extremely unlikely to happen.  Generic protocols and multiple conformances are listed as unlikely in the generics manifesto.  This *exact* use case is cited as the usual motivation for this feature and deemed insufficient.  

If you want to see generic protocols and multiple conformances I think you're going to need to provide extremely compelling use cases in order for that proposal to be considered.  And I would be surprised to see it make Swift 4 even if you do find sufficient motivation.
