If you're just *reading* 8" images it should just be a simple matter of
remapping the pins.
Here's a good reference; just reverse your perspective:

FWIW, several dual-mode FDCs, notably Cromemco, effectively duplicate
almost all of the relevant 50-pin signals on their 34-pin interface, so no
mods or adapters required. In fact, many people use 3.5" and 5.25" HD
drives (and presumably Goteks) on the 34-pin cable and they appear as 8"
drives to the system.

FWIW, I just received a Gotek last week and it
uses an AT32F415.
The first one I bought many years ago has an STM32F105.
At the time there was no third party firmware and it turned
out to be pretty useless on anything other than a PC.
With the current hXc2001 firmware it looks to be usable for
any of the disks I may want to replace.
I just got two new ones and they have AT32F415 chips.
My understanding is that the two are functionally identical.
We shall see as my fun progresses.
An interesting note. I have a device from DBIT that lets you
hook up an 8" disk to the interface for 5.25 or 3.5 floppies.
I wonder how I would go about reversing that process so I could
hook one of these GOTEKs up in place of a physical 8" disk.
