Before I comment further, I want to say that many of the ship-sets contain beautiful work and are inspiring to say the least.

Believe me when I say that I have no wish to offend or decry anyone's work.

I intentionally drew some rather strange comparisons for the sake of getting folks attention. But the idea is that form follows function.

I'm not sure that I agree that a 100 ton difference in carrying capacity necessitates or warrants turning a blueprint upside down. But a 200 kt transport may be able to dock directly with a space station and therefore it's design would take docking into consideration.

On the other hand - a 300 kt transport may be too unwieldy to dock directly at the same station. Therefore some design changes could/would be made to facilitate off-loading via shuttle and certain protuberances, etc. allowed which were not on the former vessel.

BTW - this is only my opinion and leanings. If you like identical twins or strong family resemblance - keep to it.

Family resemblance, however, may be arrived at by using standard components such as engine pods, cargo pods, gun turrets, etc on radically different chassis designs.
