Is there anything smaller than mini-itx's 6.7x6.7 that still has a pcie x8 or x16 slot?
I know intel has there 5x5 standard, but it doesn't have pcie, just m.2.
as long as they are pci-e 3.0 the difference is less than what you'd expect.
The only alternative I believe is going MXM form factor, asrock suggested something like that recently but I don't know if it will ever become commonly available.
The techpowerup test recently linked in the PCIe Bifurcation thread (https://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_1080_PCI_Express_Scaling/24.html) shows a GTX1080 taking a ~8% hit in framerates at 1080p resolution at Gen3x4 vs. Gen3x16. It's not miniscule, but it's not grotesque, either. Put in perspective: if you would normally get 80fps with a 1080 at x16, you would still see ~81fps at x4.
I answered to that, if you combine the size of mobo+gpu and MXM is a viable solution for you, yes. Otherwise AFAIK, no, but I leave that to the SFF gurus.

Put them end to end and have a really nice gaming rig in a space of 5.5 x 2.4 x 14.1 inches. or just barely over 3 liters.
There should be room for some ssds under the gpu.
You'd need 2 power bricks though, one for the motherboard and one for the gpu.
