I am expecting Epic 2.0 within a year, and they might have new ideas for upgrades.

This hardpoint would add a device slot, and allow you to launch bombs at 3^ (or only 2, 1 would be too close) from the (presumably added) center hash marks on the section its mounted on. That is, 4 options on a ‘small epic’, but only 3 on a Raider or CR90. Maybe make it like Ordnance Tubes and bottomless ammo, or keep to the existing charges.

while this could be deadly on a standard sized platform, the lack of maneuverability of Epics could help make it less dangerous.

Yes, there is the Cluster Bombs cargo slot, but that’s a reaction, and takes up a different slot.
