OK I can buy that..you are the designer after all, only you know what was in your head at the time of the race naming, as such are THE definitive source.
Though as far as the WYN go..that is a bit of 'astronomically' high amount of coincidence that the WYN star cluster as described can be correlated to an actual star cluster with similar properties which was observed by a guy name Wynn.
That's "go buy a lottery ticket" sort of dumb luck.
and yea, its true, the Lyra and Hydra constellations do NOT line up at all with the Lyran or Hydran spaces in the game (in face the primary star of Lyra (Vega) is right in the middle of core Federation space).
Orion, however, is right where it belongs (of course the original Franz Joseph map of the galaxy in the Star Fleet Technical Manual is based on the real deal.)
Still, having no less than 5 races who happen to share a name with the constellations in a starship combat game is also pretty unique as far as coincidence goes. A couple are coincidence, 5 is a streak but I imagine its hard to be in this genre and NOT be influenced by cosmology, even unconsciously.
