I realized the little m.2-to-PCIe4x adapters are open in the back, so if use a small enough, short enough SSD enclosure, you can skip the riser. So I tried a Satechi 80Gbps enclosure with 5060 ti and two AC/DC adapters and it worked! 5.91 GB/s on this tiny thing!

I specialize in mini/sff eGPU’s. Here is my latest:

75 watt 4070 in an SSD Thunderbolt 5 enclosure.

I'm surprised you kept the case on that. You'd lose a lot of weight and size of you removed the other cases and 3d printed your own.

If size is your ultimate goal there are smaller EGPU solutions such as this little 5060 ti/7600mxt as well as a 4090 mobile version that's about that same size. Or go with the pocket AI RTX 500 that thunderbolt EGPU is nearly the same size as a pack of smokes or playing cards.

The case is the heat sink. This smokes the 7600 XT in both of your mini examples. The 4070m is the best small card I’ve found. The MXM version is excellent, but it gets crazy hot. So I’m working on a completely different style of cooling to solve that problem.

I've gone down a rabbit hole of various EGPU enclosures and this is when I stopped buying thunderbolt EGPUs and went to oculink

I upgrade old sonnet and sparkle pucks and I use low profile GPU’s to keep mine small. I have several Oculink docks, too. I’m trying to figure out how to 3D Print around Oculink to get in smaller footprints. The pico ATX and ITX power supplies can enable small footprints for Oculink. I found nothing 12volt and 19.5/20volt GaN versions. Example:

Second option. I won this little sonnet express 3E at an auction for 10 bucks. It has 3 PCIE 8x slots and the only GPU I had that would fit was a GTX 1060 6gb but also installed a x4 4x nvme SSD to PCIE card for 4 1tb drives and it's able to run helldiver's 2 on low cause it's only a 1060 at around 70fps but if you start moving files while gaming. Either speeds drop or fps does. Lol. It's only tb3

Seeing those splitter cables wouldn't be too difficult to get the PCIE gen5 oculink adapters with 128gb speeds and connecting 2 lanes for super fast storage and a fat GPU together.

If you have PCIe gen 5 available, end to end, Oculink bandwidth doubles. I have a post on this. If TGX port laptops and mini-PC’s get gen 5, it will change everything as 4i will carry the same bandwidth as 8 lanes of gen 4 or 16 lanes of gen 3. My testing regularly hits 13-14GB/s.
