My hitch rack has an endcap that you're supposed to remove so you can slide in the +2 extension to accomodate 4 bikes.
I don't have the extension but I am considering building a big metal bumper that I can slide into place. Delta used to make such a bumper for their now discontinued Bikehaul rack. I'd make mine bigger of course...
And maybe mount some rearward facing reactive armour to it.
