I don't think we should look at the scientific point too much. I mean, Freelancer has sound in space. That's weird enough as it is. Also, the French are powerful and figthing. Another thing that, according to science, is impossible.
The idea on its own is pretty neat. It's just, 'how'? Maybe ask Treewyrm if anyone wants to try this out. He managed to give the Iota nebula's a new look (mainly because they were actual paintings...) so I'm guessing its possible.
