Then I must be confused by what you intend by your redesign (which I know you wouldn't prefer to the original ship). I guess I'd need to see it to see what you're talking about.
No problem...
First, the side view. The pylons are longer, and thus more mechanically secure in the direction from which they'd be loaded when the ship accelerates or decellerates. The dorsal section looks identical from this perspective, so no "tweaks" are needed here.
Second, the front view. The pylons are the same thickness, so they'd be the same from this view of course. (I wouldn't object to adding a LITTLE more thickness to them, but I dont' think it's necessary)
However, instead of one vertical "dorsal" you now have a pair of sloped dorsals. They go from the centerline of the secondary hull to the ends of the impulse deck.
That would make for a far more mechanically robust ship, but the overall appearance would barely be affected at all.
By the way, I've done these using the Casimiro prints as my basis.
