I like this one!! What about doing a Reman Scimitar like the one from Star Trek: Nemesis?
Sona's ship would be an awesome model to do, but is probably even more complicated than the scimitar. What two ships were you considering?that would be a challenge! I guess thats too high for me! A Valdore would be more possible, but i had an eye on two ships of ST:IX
