So, is it possible? Any suggestions?
Yes, in general.
It will depend completely and entirely on the game you wish to extract the models from.
"from games" is a bit too wide in scope. You might want to mention maybe -a- game that you want to extract models from
There doesn't appear to be much modding of the game, which generally suggests encrypted code/assets.
I don't own the game so I can't say for sure, but it's possible you can, more than likely you can't. Not without some hard effort, at least.
Do you think, i can add a topic to the ship submissions with pictures like this?

I don't think so. Since we have de facto "no imports" policy here.
Post scriptum: this one would require hell of re-modeling and re-texturing to make it more disco-like.
I see. Still I'd love to have the 3D models
