Would sins ever see local grav well super-weps similar to death stars?

Being able to take out a cap-ship via death star super laser was a very cool feature of the star wars universe.   

Would the sins universe ever feature something like this?

Also having 1 off super-ships like the super star destroyer was another cool feature too. Personanly hoping the sides will each get there own super-cap to act as a proper flagship
