HBC shots aren't traditional aoe, no, but if they kill the first target hit the beam punches through and hits anything behind it, and so on. Same deal with the HBC modules on spire capital ships.
If that's the case, but they rarely seem to be able to "penetrate" due to them having trouble landing the killing blow, they may need a decent damage increase, possibly with a small fire rate decrease to keep DPS from getting out of hand.
Sure, their single target efficiency won't change much, but they would be more likely to actually take advantage if their shot penetration effect when they do fire, meaning they become more effective on groups of ship.
Also, increasing number of lasers per shot may be worth looking into, but not too much without some per laser damage decrease or fire rate decrease, or else DPS would get out of hand.
