You are probably joking, but in case you are not the play on words only works in this particular configuration (present tense, "a Swedish tiger" vs "a Swede [keeps] quiet".
Sadly no, but good effort! What you wrote would literally translate to "Silence your of Sweden". If you want hush, I'd probably use "tyst" instead of "tig" as the former is more colloquial. If you squint and have a bit of an open mind, maybe you can construe your sentence as something like "Silence, you Swedes!" but it's a bit of a stretch.
i.e., Hush, y'all!
