As far as I understand it, this move isn't supported by either Apple or VMware. However, there are many hackers on the Internet who have reported to successfully installed OS X either directly on their PC or in a VM like you're trying to do. One article at Online Tech Tips states in a comment (emphasis mine):
Best fix for display resolution is to get the darwin.iso containing the Mac VMWare tools from a VMWare Fusion installation off a MAc (it’s under Library/ApplicationSupport/Images.
It's actually under /Library/Application Support/VMware Fusion/isoimages on an OS X machine with VMware Fusion installed. If you can get your hands on that iso, you should be good.
