I'd say the easiest way in this case would be to rework laser miniaturization.
make it 4x and 16x reload instead of 5x and 20x, and add some new tech for 33% at 48x and 20% with hangar reload of X seconds, or maybe just make it a 150x or something.
As for those missiles, given the duration of 1 second, they'd be only interceptable by point blank defense fire.
Now those things could just be calculated after other missiles, so only left over Firepower shoots on them, and you could not swamp enemy Anti-Missile systems with it. Or just make them non-interceptable, Beam weapons aren't, either, and this is essentially asking for small beam weapons having a bigger punch/ time in exchange for costing ammo.
Quite the opposite of Plasma Torpedoes, which are having longer reload times in favor of not using ammo.
However it gets implemented, I think it's a logic step, and will allow for more weapon variety.
