Is It Possible? What will happened to the band? or even its possible that the band will never existed?
Rammstein are fiercely anti-Nazi and their worldview was shaped by their members growing up in the totalitarian shithole that was East Germany.
They'd likely be underground, subject to harrassment (like Feeling B and... whatever that other pre-Rammstein band was) and even more outspoken about their views.
Hell, it'd be awesome if "Links 2 3 4" was actually an underground anti-Nazi resistance anthem.
