There's a lot of room between the near ms turn on speeds with a weak pull-up resistor and the 10's of ns you might get with an uber driver on the FET. I would not cost reduce the series gate resistor out of the design.

You have to get to around the 250 piece level to move the price on the chips from the $1.xx to the $0.7x level. I was looking at the volume price earlier. The economics of getting the pc boards made are even worse than that volume wise.
