The ears are the worst offenders here, IMHO, and the overwhelming similarity with the Hecate at first glance doesn't help. The ears just seem absolutely useless, as Alakabeth pointed out. I also agree with the suggestion of creating a series of platings protecting the Meson Bombs. You can make them with some openings so that someone can "visually guess" what is there inside. I imagine a series of these plates like thin faceted rings illuminated by the insides of it.
The idea that it doesn't need armor is flawed, IMO. If it is to be used as node-busting, then surely the assumption is that the other side of the node is already compromised and filled with shivans. To use this ship without any armor is extremely risky and fragile. It won't survive any random sortie by shivan bombers / fighters trying to suppress any resistance to the node invasion (see Flaming Sword, etc.).
However, regarding the concept, I think it's a really cool, obvious and useful idea for a "TEI" post-capella ship. Node busting is surely the only possibility of survival against the shivans in the medium term, and I also like the idea of it being automated. Perhaps adding a "robot AI" .avi (.gif?) to go with it so that it may be used when "it" talks to us in-game would be an awesome bonus. However, it can also be used as a ramming ship against a Sathanas, etc. (ala Derelict)
