Could we make a system like Avatar movies Alpha Centauri?

I was wondering how much of these could be done in Empyrion, I know there is a scenario editor and a universe editor and world editor, I used them a few years ago. Now I'm wondering if any of the following would be possible to do based on the Avatar movies:

1. A system like Avatar movies Alpha Centauri with 3 suns and all their planets and moons
2. A blue gas giant like Polyphemus with its 14 moons
3. A moon planet like Pandora with bio-luminescent flora and fauna
4. A scenario where a corporation like the RDA keeps invading the planet and you are allied with primitive blue native aliens who try to defend their planet
5. I don't think we can have floating mountains, waterfalls, or giant trees right?
6. There is no water fauna either in Empyrion right?

Any estimates of how many hours would it take to do all that, or if not all that, as much as possible.
Has anybody done it yet?
Thanks

 

Yes,, most of that would be possible, to varying degrees, usually using some workarounds.

Probably looking at hundreds, if not over a thousand hours.

 

Thanks for the reply. Hundreds to a thousand hours wow I didn't expect that, but good to know. I think I'll just wait for the ubisoft avatar game to come out then
