One thing that occurred to me yesterday:
A base GR-75 with Leia and Repair Crews is a mere 25 points and is superlative for "oh crap" moments where you'd like to both remove a damage card from a heavier ship and set its command to Engineering to start regenerating shields like crazy.
Leia in general seems like an easier fit on a GR-75 than a CR90 and due to their fleet support role it shouldn't be difficult keeping them close to use her ability. An alternative setup would be the Comms Net upgrade + Leia. You reveal the dial, convert the top dial of another ship to the desired command, turn the GR-75 dial into a token, and then pass it off to someone else. Combine those abilities on the same ship and you've got an on-demand Raymus Antilles dial+token. Pretty sweet.
