Is making an MXM egpu a fools errand?

Hello, I am new to this forum but I have been really mulling over making a smaller form factor egpu out of an mxm card, but heck... Im not even sure if this would work.

From what Im seeing, they dont make adapters straight for mxm so i would need:

EXP GDC or equivilant that goes from pci-e 16x pci-e 1x
connecting that to a MXM to PCI-E 16x adapter.
Then in theory taking the pci-e 1x and somehow getting that into usb type-c or usb 3.

I was planning on jerry rigging a laptop battery for power with a heck of a lot of cooling, but I havent a clue if this is even a fools errand or if something is completely wrong with my line of thinking.

Any wisdom on this?

Probably. Finding MXM cards is a hassle and in most cases, you're better off with a "real" GPU for the money. Also, it seems kind of odd to put notebook GPUs outside of the notebook (ie, eGPU)! I suppose you could try making a battery powered eGPU? That would be kind of cool.

I was thinking the same thing. The only thing is that my use case is a coffee shop egpu, so weight and size is more important to me than a bit of clock speed. 

I've been looking to find something that I can throw in a backpack. (With my personal laptop and work laptop that I commute with every day) 

That being said, I know that there are people selling just laptop gpu sockets(for the lack of a better term), but I haven't a clue if there is something to nest one in, so I was leaning towards a mxm card, even though they seem like a nightmare to deal with.
