STH has reviews on the AIC JBOX, and the Microchip SwitchTec PCIe switch chips.
At least in principle it sees possible to go from a single PCIe 5 slot to 4x PCIe 3 ... but I must be searching wrong, as not finding anything. Is this strictly the domain of custom hardware design, or is there off-the-shelf gear available? That would allow using the current Zen 4 CPUs.
The 4x PCIe 3.0 x16 Xilinx FPGA cards are to host existing firmware (so not looking to re-do the cards).
Otherwise would need EPYC, and some sort of expansion chassis (like the AIC JBOX) to fit the fat FPGA cards (and possibly a GPU or two).
Edit: Seems to key is to look for PCIe expansion chassis. Perhaps similar:
