Not really. At least not on a naive level. None of "pv zk bschk pv zk pv bschk zk pv zk bschk pv zk pv bschk zk bschk pv bschk bschk pv kkkkkkkkkk bschk" occurs in any German word.
Yes, that's what I was trying to say. But since it's not compound, it's not as bad.
By the way, if you want a genuine example of strange sounds in German look at Herbst or Pfründe.
Fun fact: If you can pronounce Streichholzschächtelchen, you automatically gain German citizenship.
I had a phase, where my German looked much more English---I put spaced inside compound words and did not capitalize all nouns. I should try capitalizing all Nouns in English one Day.
