Just about everything looks better than that dead metal fish.
The problem is that it is a design owned by Activision.
So it cannot be used by another company because of the licensing issues.
Besides it's not a carrier, it's a cruiser/combat support ship.
As for thenaming similarities:
The Klingons named the creature that guards their version of hell after
the species, then pretty much forgot about the connection and then later
named that ship after the creature.
So it's the Klingon cruiser/surrport ship Fek'lhr and the Fek'lhri carrier Kar'fi.
