Not so much cartoons, but Nerf Herder has a lot of good material you could probably use. I'd recommend 'Mr. Spock,' 'Manatee,' or 'She's a Sleestak.'

Another option I could recommend is an album a buddy of mine bought called Faux Real. A bunch of bands I've never heard of cover the songs that fictional bands play. http://www.wired.com/2014/03/mystik-spiral-dr-teeth/

John Cougar Concentration Camp has a song called 'Half Assed Jedi' which is right up there with 'A New Hope' since that was on your list already.

I think a lot of Aquabats could count, particularly songs off Charge!! I'd recommend 'Nerd Alert,' 'Stuck in the Movies,' or 'Awesome Forces.'

I think there's a bunch of internet famous songs you could cover that would go over well also. Lemon Demon's 'The Ultimate Showdown' is one that comes to mind right away.

There's one of those lame corporate pop punk bands that does a song called 'Hey Mario' about the plumber that's actually pretty catchy if you don't mind something on the pop side of things.

I know there's way more could think of, I'll give it more thought and edit my post with updates.

EDIT: That was quick, there was one right at the back of my mind

Also if you were comfortable covering a little bit of rap there's some great options also. Weird Al's 'White and Nerdy' and anything by Starbomb comes to mind.
