Quite simple, if you could swap out an upgrade slot on a ship for a different one, which would you go with?

I'd swap a Torpedo slot on the Y-wing for a bomb slot or a crew slot.

Related, I have been toying with a house rule Y-wing only modification that removes the Ion Cannon Turret in favor of either a crew and/or bomb slot, at cost -1.

Swap out the missile slot of the YT for a droid slot. R2-D2 droid on the falcon.

Swap the title slot on tie fighters for almost anything else?

Removing the turret would seem the logical choice for converting from a BTL-A4 (one seater) to a BTL-S3 (two seater) but that would prevent Recon Specialist/Blaster Turret.

Maybe the crew could be installed in the mod slot?

Totally misread the word "slot," so my first ideas, which mostly involve Kath Scarlett, are wildly inappropriate.

My first thought would be to allow "secondary weapons" slots (missiles, torpedoes, bombs) to be slightly more interchangeable, such as being able to carry multiple bombs on a bomber or Y-wing.

I'd probably drop one of the torpedo slots on the bomber, for another bomb slot.

Missile slot on the Advanced for a systems slot AND an extra mod slot... call it "Jury rigged Prototype"

Mod slot on interceptor for an EPT (for Royal Guard Shenanigans)

I'd probably drop one of the torpedo slots on the bomber, for another bomb slot.

This... lol

I'd drop a cannon slot for a turret on the shuttle.

Do something to give an A-wing a system slot, possibly a Mod or similar to the new upgrade, drop missiles for a System.

I'd drop a cannon slot for a turret on the shuttle.

This, but then i'd be flying a 37-40 point shuttle, thats forced to focus every turn
