The idea of it being a repair ship that has less bots/bats and an improved ability to defend itself is the best idea I've seen.
Kishiro has many structures it has built (particularly for GMG) on top of the civilian ships it produces. These ships would make great maintenance ships for both the structures (in RP) and ships (in PvP) that would need them. Since much of Kishiro's latest developments are in the more hostile borderworlds (Sigs and Okinawa) the more agile and better armed/armoured repair ship would be great addition for that area of space.
This hasn't taken into account their use in the backlines of the war either.
