Add an option to remove the pontoons on the sides of the 2S38. They are ugly. Thats it pretty much.
I dont think its gonna be that much out of place, especially considering that the AU-220M turret was planned to be slapped on many hulls, one of which is the BMP-3, with the 2 together being called the “2S38”, and those pontoons not providing any part to the name and only being practically an add-on.
There are also photos of that system without those pantoons, and its still called “2S38”, so there is not even a historical reason to not be able to remove them.
