Can these be made into a plugin?

I've been looking for tree models online and I came across a file called "Prehistoric Tree's" here:
http://tf3dm.com/3d-models/trees/1/obj
File is too big to attach but it's a collection of .obj files and a few other .png's among it all. Would it be possible to turn these into a singular plugin that would work with Rising World, or should I keep looking?

Theoretically: Yes. Practically: I recommend to look out for other models These models were obviously never designed for games, they have way too many polygons. The trees have between 70,000 and 90,000 triangles, the ivy even has more than 900,000 triangles This is way too much for a game, or more precisely, way too much for a single plant in a game. Just as an example, the trees in Rising World have between 1000 and 7000 triangles.
Most of the online 3d pages offer models which are mainly designed for rendering purposes (so they often have many polygons). When rendering a video or a screenshot, it does not really matter how many polygons the scene has, even if the rendering process takes a whole day (remember that the game has to render the scene multiple times per second, if you have 60 fps ingame, the scene is rendered 60 times a second).

Thank you.
