German Twin-Barrel Tank Destroyer tech-tree suggestion!

Einzelganger7: I feel it would be similar as how we tend to rotate the Hetzer since it has a weird cannon traverse for being on the right side. But since these VT tanks have no traverse, the cannons are pointing straight , I'd like to see another angles of them, maybe from above to see if they are completely parallel or angled slightrly to the middle, you know, something like this (terrible paint skills, I know lol).  
But if they are angled to the middle, I think they won't suffer that much at mid ranges, they would at close range of course but not as much as if the cannons were completely parallel.
