Of course it can. We have the Churchill crocodile and M1A1 Flamethrower in game already. I guess its just if someone wants to or can adjust the hull MG a tad bit to make it into the flamethrower, then its about coding it. It is not impossible thing to do, its just about if someone wants to do it and if we really need them. Ts4Ever might have some more insight on if this is something that may or may not happen since he worked on Seelow.
