It shouldn't work, as it depends on source code used to make that SystemUI, and then, also on the one used on the ROM you're using.
Think there's a simpler way: every CyanogenMod supports the Theme Enginer, that allows you to apply themes for every graphic part of the system. Just try to search for a SGSIV-like theme and use it!
