Greetings and salutations,
Micka, Kafka, Liam, Mal, and others, as I see it, the 2I starships would have been heavy in Solomani designs. However, if Ziru Sirka designs looked Solomani enough or could be modified to look Solomani enough, I think they would have been put into use.
Case in point:
Had a PC whose character was a Naval Ship Designer in his career so he would do a few drawlings to give the rest a hint of what the ships looked like in MTU. When polities went to war against other polities, designs were taken by the victor. New designs not built by the loser were evaluated by the victor. Some were used as is, some were modified to look more like the victor's ships, and others were just trashed.
