Um. Im not sure if you need to do all that.
I came up with an invisible icon set and background last week sometime. All you do it load them into HHC and it shows the same way.
Heres my screen. Should hold on soft reset too.
Stoths that space is still gonna be there. If his is somewhat the same as mine the icons are really still there just not visible.
EDIT:
heres the post.
