The IMG one could work, shoot a PM to von Gotteshand, one of the major people with the [IMG] (the =CR= are NOT IMG...)
The Liberty one would have to go through the SA, and with Korrd's recent authorization of KoS'ing people who "steal" ships from player factions, I don't think that would work. Less so with Bretonia, they aren't just preparing for war, but actively warring against Kusari and would never let go of military hardware.
Stick with the gunship, go to the Orca (ehh...) or ask for the IMG.
