Alternative builds with Star Wars LEGO sets
There is a website, http://rebrickable.com/, that lets you enter the sets you have, and it compares the inventories to other sets to determine which other official sets you can build with those pieces. It also includes unofficial MOCs that other builders have submitted, and it will substitute other part colors if you choose.

For example, just entering the first six sets on your list, it suggested a mid-sized (360 piece) TIE Interceptor MOC (http://rebrickable.com/mocs/anincompoop25/tie-interceptor) for which you already have all of the pieces.
