@JDCollie: Welp my linguistics professor is wrong then, ah well
@ORMtnMAN It's not readily obvious because I haven't expanded the fluff yet but the idea is that the Scion virus is very adaptable and because of it's ability to overrun practically any ship it has a great deal of variation in it's available tech, so the Scion collective's ships will be varied from mid to high tech in general. But with fewer midline ships as a general rule. The fact that they don't all 'look' high tech is mostly just coloring and your existing preconceptions from having played the game. If I had the patience and skill to recolor the sprites blue they wouldn't look as out of place.
As for your offer of kitbashing assistance it's appreciated, but unnecessary, I'm fine with doing the actual kitbashing, in fact I quite enjoy it, it's the code in the background that I need help with.
Finally I'm probably not going to update the mod until Alex releases the next version of Starsector, if only to cut down on the workload
EDIT: The engines on the Tomb class are from the Paragon (I think...)
