Any thoughts on this? suggest any changes.

yes please, will take all 3 with immediate effect

Only change would be to the Dreadnought, has to be Rare rather than ex.rare, so it keeps in line with the current troop carrier, as it is effectively a replacement. Otherwise with Dan and his ex.rare and insane spawn rates, it would have a 1/5k npc's spawn rate.
