Theme creator/editor

[Daddy4Kawaii]

Is there or will there be a theme creater/editor software soon?  I like the black system arcade theme but I would like to change the background image of it (possibly font and font color as well).  Also I'd like to use different sounds and use a boot-up intro video.  I love the simplicity of this FE (very user friendly and nice over all) but these are the only things I feel is missing.
