According to Wookiepedia the GR75 is equipped with 4 turreted twin lasers - standard!
What do you think (for casual games of course) about adding a hardpoint slot to it with a front turret ... maybe at the cost of a cargo slot or modification that costs a few more points?
Unfortunately the current hardpoint upgrades don't offer a twin laser turret and Blaster Turret upgrade won't work here (no focus action).
So how do you imagine the twin laser turret? Range 1-2 with two red dice? Or rather range 1-3 (as with the CR90 quad lasers)?
Would that make the transport more interesting or less unique?
