I don't know why I feel happy about it, but for some reason Renesas still manufacture some variant of their "QSpan II" Processor-to-PCI Bus Bridge, which has native support for the 68040 bus. They are bit pricey though.
Theoretically, one could build a PDS'040 <-> PCI bridge board to be able to use a PCI device in a Quadra. And there's still some PCI <-> PCI express bridge being manufactured, so even PCIe is theoretically possible. That or using the GTP pins from an Artix-7 FPGA to get PCIe directly.
Of course the lack of software support is the show-stopper. But it's a nice thought.
Happy new year!
