Why not, in the next GFDL version, just remove the clause that says you have to include the entire license, and just say it's sufficient to state that the material is GFDL and credit the author(s) in the appropriate manner? Wouldn't that - for the everyday person - accomplish exactly the same as switching to CC-by-SA?
I think FSF's modifying the GFDL so that it is a functional equivalent of CC-BY-SA is a possible path for FSF if they want to respond to the Foundation's request.
