All the logistical burden this engine would cause aside, why does the ship need to be transfered to a Kishiro facility? I'm sure the Hogosha would have vastly more experience in that regard. After all, they've been using our tech for a few years already. They ought to have figured out how to best adapt kusari equipment to ours.
Not to mention that you actually want to hand a piece of our tech to some corporates. We wouldn't really appreciate them digging in the ship's guts, would we? But, I do not suppose a person of your competence has not thought this all out.
