I like the idea of having a rag-tag fleet of random ships I've accumulated from minor civilizations, the market, and random events.  The problem is they are very quickly rendered obsolete.  I would like to be able to upgrade these random ships periodically.  Perhaps only with the "auto-upgrade" option?  This would allow modernization without the customization offered on ships that I can normally build.


Frankly some of the random ships I accumulate look pretty cool, for example, the Sword, the Knife, and the Shuttle.  Perhaps the ability to refit foreign technology could require a Hero assigned to the fleet?


I think this is particularly important for ships that I go through the trouble of capturing during a battle.
