Change Oracle SQL Developer theme (add new ones)

view story

http://ubuntuforums.org – I was using MySql Workbench for a while and had to use Oracle SQL Developer as I migrated from MySql to Oracle... I found that SQL Developer was the GUI Client for Oracle server, Is there any way i can change the boring theme and add new themes like Mac OS X, Equinox to it (I KNOW THERE ARE SOME THEMES INSIDE PREFERENCE->LOOK AND FEEL ..... BUT I WANT TO ADD SOMETHING ELSE, THEY ALL SUCK) ... If nothing can be done other than the default ones then can i atleast need to change it to match my Default Ubuntu theme (Hardware)
