Well, if this is a Frontier fishing expedition, I'll toss my "Pocket Carrier" back in (Large-pad dockable, Small pad on topside, carries 3 Small ships, can load ships to/from station ship storage while docked) and suggest it as a possible solution to the Fleet Carrier "one ship per CMDR" problem.
Load up your Pocket Carrier with 3 Small ships, dock it on your Fleet Carrier, and unload. You now have 3 shuttles onboard which you can use to go fetch other ships with. Repeat as necessary.
