It would be really funny.
The Gun has the traverse of 0 to 70°. But the firing elevation was 55 to 70°. According to Tankencyclopedia. They say that the 60 cm gun with only 1 charge and heavyest shell had around 2.84 km range. So technically workable if you bring it to top tier and get a bigger map? And well the 54cm gun is out of the question.
I don’t know if lower then 55° firing angle would destroy the vehichle, but I kinda assume. That said If we want to bend reality for gameplay, than the gun depression is 0° I guess. Now the way more problematic part is If it even had any HE shell proposed, because With only anti-concrete shells, we ain’t gonna clear caps.
They bent reality for gameplay with the SturmTiger, so it’s possible
