Still think it would look appropriate as some sort of Sci-fi vehicle.
Other pics I've seen of this tank gave the impression that it was quite a large one. Seeing the figure beside it, it doesn't look that big at all ---
Ditch the turret, sand down & fill the turret ring, add a few greeblies over it, too, & scale-o-rama it to either 1/72nd or 1/144th, with the drivers periscopes acting as command/control centre view-ports.
You now have a very big sci-fi exploration (or similar) vehicle.
Mind you, as a whiff, I wonder how one would go replacing the twin tracks with a single wide track?
I'll let you make the tracks for that, mate!
