AHHH that would be cool! Very possible if you ask me.
Paludarium (part submerged, part emersed) or vivarium (same, but less water) tank is what you would look into. Have seen fog machines used on those as well. Not sure how filtration systems are set up on those.
Not the best at recommending plants, so I won't.
You could try and find nice driftwood, or possibly make a 3D background with foam/fiberglass sealed with non-toxic epoxy resin and paint it up nicely. Lot of tutorials out there to make them look realistic. Might be your best bet, as real driftwood might be challenging to find the right style pieces and be able to mount them securely in the upright position.
Just make sure the X-Wing isn't toxic :P
