I highly doubt it's a good idea.
The Nazi era has cost countless of lives and people have not yet dealt with it.
It's like me opening a restaurant in america and offering the "14 trillion debt" sandwich.
Still, imagine he opens up a restaurant for April Fool's in a prime area of his town. People who can take a joke would probably laugh and go inside, to see the menu. Technically, the names are German-themed WWII terms and have nothing to do with Nazis, so it's not illegal or hateful.
It doesn't matter if the intentions/names are neither illegal nor hateful.
In German law, the holocaust was neither of these and it still didn't make it right.
