STAW practically didnt do anything right so its kinda hard to use them as an example.
The only way i'd see FFG adding dice to this game due to having to include the dice is another core box with ships using something else instead of red. Which, is after all, entirely possible. Ship primary weapons dont need alternate colors, just secondary weapons. Or an upgrade that says "When you perform a primary weapon attack, roll 1 additional blue die" so youre rolling a mix.
