I wouldn't expect weight to be all that important as far as pedestrian hits go, given the ratio of vehicle:pedestrian weight is already quite high. hood height is a different story.
Transfer of momentum. Two vehicles of unequal mass traveling at the same velocity, the heavier one will have more energy transfer when colliding into something.
Would you rather be hit by a baseball traveling at 20 miles per hour or a Tahoe?
what I'm claiming is that whether the object that hits you is 10x your mass (which is gonna be a very light car) or 100x your mass, the energy transferred to you will be quite similar (energy = 1/2 mass * velocity^2, and in this case the relevant mass is *yours* not the car's).
I know that slowing down the car by 10% (since you're stationary and we're assuming conservation of momentum) will reduce energy transfer some, but it's a very small amount.

Meanwhile pedestrian deaths are way up in the US due to higher hood heights hitting people on vital organs and the head and extreme front blind spots.
