Personally, I think that is an overkill.
Once you prove you can do 1-4x Gen1/Gen2 (which is currently
prototypable on low/mid range FPGA's), you can scale your design by
increasing the memory bus width and the host bus interface.
There is no need to compete with AMD/Nvidia in that high-performance
segment.

Standard PEG 16 and support gen 3. Though I admit an x4 gen 3 would
probably service the actual bandwidth needs.

They make adapters, but unless your current board has some unusual
feature you really need, you're probably better off getting a new
mainboard, and finding some other use for the current one. :-(
There might be a few OGD1 cards (PCI-X) still available.
At this point PCIe has been out for several years, so I assume that
the market for PCI or AGP video cards is very small. (Is anyone else
wanting PCI or AGP? If so now is the time to speak up.) The bus
interface is different, so it would be a significant change
to the electronics.
I have seen photos on the web of cards with one interface on
one side, and a different interface on the other. I suggested
that for OGD1 but there wasn't interest.
Given our limited resources, I'm trying very hard to come up with
a single board that can serve as many people's needs as possible,
without raising the cost (in engineering time, economic cost,
or risk that something will not work) too much.
Perhaps someone will to volunteer to design a 2nd board with PCI
or AGP, or to do the work looking into the possibility of
having two interfaces on one board.
