it would be nice to come up with something new, but i don't think anything was ever thought up that could fit.

it'd be interesting though if whatever 'DS2' was changed to, could relate back to the PT somehow, like dooku had developed a superweapon, or uncovered one. maybe a facility of droids which were super kick ass (like if grevious was a prototype).

thing is though, it'd ultimately be a superweapon, which blows up rather carelessly due to rebel ships shooting it in the heart. so even if it was a giant space hoop called something else, it'd be a death star.
