The title says it all, does such a thing exist? It would allow Intel fans to get 10th gen CPUs without worrying about lack of support for PCIe 4. If it doesn't exist, will we likely ever see something like this or are there technological quirks that prevent a practical design of such?
Thanks!

No, while there are already PCIe 4.0 adapters (like the AORUS) that can be used in Intel PCIe 3.0 x16 slots they will not perform as well as using a PCIe 4.0 x 16 slot. If you really need PCIe 4.0 you will have to go with AMD. On the "cheaper" end (as opposed to much more $$) look at an X570 with a high end Ryzen 3000 series CPU.

There are bandwidth issues that cannot be overcome with adapters -- at least not that anyone would buy so...

There are bandwidth issues that cannot be overcome with adapters -- at least not that anyone would buy so they will never be made. If you live for benchmarks, PCIe 4.0 is important, but the actual performance that can be seen by a user will not be any different, pretty much like putting 4 NVMe drives in RAID 0. There really is no realistic point, although you can get great benchmarks.
