[Tahlan Shipworks] Any way to get more Legio/Nightwatch ships with the Legion disabled?

Maybe a weird question, but I had them disabled in my game due to not wanting to deal with all their OP Daemon stuff. However, I'm a ship collector at heart, so I was wondering if there was any backup ways to obtain these ships, especially the Nightwatch ships?

Side note, any idea how to find the Ark Metallican or Red Guard ships? They both look cool, but can't say I've stumbled upon either. I found the baby cruiser version of the Ark, but not the Ark itself.
