Once we start that game, we can also add the weight of the Mirai's 1.6kWh NiMH battery and other esoterica.

The proof is in the pudding: the curb weight of a Mirai is more than that of the larger and more capable Model 3.

How important is weight in their designs though? They're cars, so they don't have to hold themselves up, and they probably both have regenerative braking

You are right, weight isn't extremely important, especially with regenerative braking. It is only interesting in the comparison with battery electric cars - if the hydrogen car is even heavier, then there is basically no advantage left for the hydrogen car.
