Sorry, was busy doing other things and upload took a while, but here is a CWM-flashable version of this ROM:

It doesn't contain Pershoots kernel as I've been having issues with it, the kernel is instead the one from the XWKG9 firmware. It also doesn't contain a new bootloader. Oh, and no radio update either. If you badly want the radio update you can extract modem.bin from the .tar.md5 file and flash it using ODIN (leave values at default and put it in the "PHONE" field). The radio in this firmware has baseband version P7500XWKG1.

Edit: new kernel from XWKH7 firmware can be found here:
