Is replacing the snub fighter on the Constellation with a third turret a thing? If not, can you pass along the suggestion?

No, I don't think that's a thing right now, and I will pass along the suggestion.

That sort of falls into the 'we need to get it flight ready first.' We need to get the snub dock working as we need it to work first, and then we can look at possible replacements. Not a bad idea, but we've got enough on the plate ahead of it.
