Removing Pieces of a Theme?

[Jubakuba]

So...I love the eagle in the lockscreen of liberty.
I love it enough to stick with the default theme even though I am NOT a fan of the yellow.
I have a teal-themed launcher pro...all of my widgets are teal.
And I would love to use the "Cyan Scream" theme, but I would love to keep the liberty eagle in my lockscreen.

I'm fairly tech-savvy...but haven't been able to find the .png in the theme .zips as of yet. I would love if someone could help me locate the eagle so I can swap it into the themes I like.
(Further instruction may be necessary...but I think I can figure it out?)

Thanks in advance!

PNG is in the framework in the stock liberty theme. You'd also have to edit a lockscreen xml to point to it.
