Well, i was thinking about to post or not to post.
Here is my opinion.
Sorry mate, if this vessel is becoming a transport class construction vehicle then yes. A no for a GB.
Simply to build this "construction frame" around was not a good idea. Why haven't you take the basic model and made the centerpart wider while cutting off the horizontal pillars left and right.
Atm i cannot see good places where to attach the turret hardpoints.
To the Kusari BC. All depends how it will come along. From my pov i can say KNF is happy with their fighter, bomber and destroyer (one of the best of its class, you will know). But i'm only a Lieutenant in KNF and i guess our Admiral would use a new BC as Flagship probably. I'm only concerned about independent players may spam this BC, but this is only a imagination. The future will prove it.
Nevertheless i'm sure you will present a very good Kusari BC model.
