Making a more realistic and even more complex Stranded would be the goal for a possible Stranded III and of course I have tons of ideas for this.
However Stranded II is finished and there will be just minor patches for it.
If you want to have a more realistic Stranded II with your very own ideas and objects you could learn scripting and make it yourself. I gave you the tools to realize your ideas! Nearly everything is possible. Have a look at Massive Mod or Extension Mod for example.
