I'd think that it's better to make the omnifighter that is designed to be intended to take the role, though. Having the temporary quirk is somewhat weird without a good reason.
...
Although I wonder that the fighter still have enough space to add the guns to be suffered by the negative quirk, but it is makes sense at least.
Oh sure, but I was suggesting it as a way to use canon units & only be a custom pod or scenario specific rule for a campaign, v/s creating whole new units from scratch.
As for the Guns, I was thinking the quirk would apply to the bombs themselves.
That weapon modifier would be to those, not any small guns the thing still carried.
So instead of applying it to an Gauss Rifle or LRM-20 you would apply it to the bomb bay.
The problem with using Cargo space for bombs is that you can't just dump them. IIRC, there are rules for unloaded Cargo from a Cargo Bay, which preclude their use in combat as a "poor-man's bomb bay".
Hence the idea to use the quirks for an Omni-fighter. The temp quirk is there to represent racks.
Cargo for bombs is exactly how they are used normally. The internal bay is set up with a cargo tonnage & the bombs fill that.
The quirk for bomb bay really should be represented by a piece of gear, not a quirk.
Based on the difference between a Regular v/s a OS-Missile Rack, I'm thinking the Bomb Rack should be 1/2 ton item.
I mean, you already get "Free" external racks at the cost of speed, so an "Internal" one should be fairly light outside of the devoted "Cargo" space.
