I like those ideas a lot Petr!! Protecting the station from the meteors is very clever and a great addition to the story for sure!!
To make the station look cool, it would be great to have fade contol of mesh. My idea. A sphere as you say, but imagine
2 hemispheric domes with central disc and cool structures inside of the dome and levels. Would be really neat looking. The sphere station has a day and night, so one side is in day and the other night.
