I agree with orin. The order needs to churn out ships quickly to recover losses, and they do not have a luxury of infinite resources either (although I will agree that the order is well funded, the purse just isnt bottomless). Anything the order uses must be utilitarian and quick to assemble.
Take the Anubis for instance. It has a liberty cockpit which I bet you can bulk order since the defender does get sold to suitable civilians. The rest of the design is very boxy and very "I can be built in a hanger by the deck crew".
Simply put the order does not have time for 'style'. They have a job to do.
