Not without giving up at least some functionality. The informal procols 
seem to be defined as categories on NSObject for at least some 
protocols, which should make it possible to generate informal_protocol 
definitions given a list of protocol names.

The current versions of the informal_protocol definitions also list 
whether methods are optional or not, and that cannot be inferred from 
the header files. Not having the additional information wouldn't be too 
bad, I'm sure Cocoa will complain loudly if an object doesn't implement 
the required parts of a protocol.
