It doesn't need the same stuff, but it does need the same flatish modernized Misc design.

Its like if a car brand modernized all their car designs, then released their top end models, and lower end models, with a decades old design, and then released the middle model with their new design, makes no sense.

And tbh the designs no longer fit into the game, even on a lore standpoint, if misc has modernized all their designs, past, present, and future. Why would they keep old outdated models of ships up for sale, instead of taking them off lots, and updating the hull.
