1, 3) In a real true complete vacuum? Don't think it could be done.
However, this's just interplanetary space, it's not a true vacuum (to an astronomer). Probably more of a vacuum than what we can do in a lab on Earth, but still, there's enough stuff there that some of my ideas aren't completely impossible. There's enough stuff that that it glows to the naked eye even (see zodiacal dust and zodiacal light), so I'm sure with a little work some engineer could really make that effect happen.
I'd call the space between galaxies a vacuum, but within a solar system and between planets is positively dense, and even between stars within a galaxy has got enough dust that it's problematic for astronomers to look in those directions in our Milky Way.
