You would still need a PCI core although you can get those a lot cheaper than 
PCIe cores. You can even get a free one from OpenCores (there is a PCI to 
wishbone bridge for example).

As far as I am aware there are no PCIe equivalents to the PLX 9054 (for 
example) - ie PCIe to local bus bridges.

You might need some information about laying out your board for PCIe 
compliance however you can probably glean that information from a PLX example 
design :)
