However, according to this estimate, a "low meat" omnivorous diet actually feeds more people than a universal vegan diet. Which makes intuitive sense because animals are part of pretty much every traditional farm system, just in much lower amounts than what average Americans eat.
As for how much lower, this study says that the vegan diet fed fewer people than both vegetarian diets and the lowest two of the omni diets. So it looks like getting everyone to eat 1/3 the amount of meat of the average American is a pretty optimal spot, at least according to this study
Of course all the ethical reasons for veganism remain intact and cannot ever be reconciled with an omnivore diet, unless lab grown meat ever came to fruition
well, I'm not a vegan, but I also don't eat that much meat, particularly red meat
