I like:
Oberon
Odysseus (!)
Tadeusz
&
Eurydice
Filomena (though I'd spell it Philomena)
Ismena
Ksenia (though I'd opt for Xenia)
Linnéa
Lucrezia (!)
There's a large Polish community near me, so I've heard names like Tadeusz in real life and have thought a lot of them sounded really cool. And for many of these I'd use the more "western" spellings, though I understand the ones you've chosen make more sense in Poland.
I remember liking Cassander many years ago, but it sounds too much like Cassandra to me now so I can't get into it. :-(
