well, the main prob with kitchen and our phones (S series and S2 too) is Touchwizz.
modifications via kitchen only affect framework-res.apk ;touchwizz needs modifications on twframework too.
knowing this, you can still use kitchen for :
-glowing (at least for sliders bars and a part of the pop-up windows IF they aren't managed by twframework ).
haven't tried mods on status bars yet with my S2 but they were ok with my old galaxy S so it's probably the same.
as always with themes, don't forget to wipe cache and dalvik cache after applying it viaCWM
hope it helps
