Taking a page from High Guard 1 (1979), I started thinking about how Traveller5 can be used to total up the effective power of weapons.
Consider a ship with ten dual barbette particle accelerators. A dual barbette inflicts 10 dice; thus, ten B2s inflict up to 100 dice.
Ten 50t bays would inflict 200 dice. Ten large bays, 300 dice.
What you end up with is a set of damage progressions. Map each of those to attack factors by weapon type, and you have something reminiscent of HG1.
