This is the MOD I made for myself and it works as expected.
I modded both SystemUI and framework-res to hide status bar system wide (not only on home screen via wanam xposed) and still pulldown option works.
I moded this on SystemUI and framework from Stock ROM.
Here is the download link: http://www.multiupload.nl/H4XBRO43QR
Flash with CWM.
It is working for me. If doesn't work, please send me SystemUI.apk (taken from system/app) and will try this mod for you.
Please note, it works both with odexed and deodexed Stock ROMs. If you are using odexed Stock ROM, please delete SystemUI.odex file from system/app folder before flashing this MOD.
