In the last years I read already a few times about the iPod now being super upgradable to an SSD or micro SD nearly as big as you want.

So I looked up the parts already a while ago on Amazon, but they were pretty expensive, so I decided to wait or don’t do it. But a few weeks ago I saw one part being available on AliExpress, so I instantly looked up the other parts and ordered (round about 30€). See below for part links (just for example). Last week all parts arrived and I started my project and put everything together. If you also want to do that, here is a link on how to dis-/assemble the iPod:
As I wanted to minimize the risk for shorts and loose parts inside, I 3D-printed two thin layers of TPU to place between adapter and backplate and between adapter and board.
I then assembled everything (without closing the case!) and restored the iPod using my old MacBook (2013 - running macOS BigSur). I restored the partition in finder and then restored the iPod with Apple Music. Tried with windows first, but couldn’t get it to work. Works like a new one now! Definitely recommend if you have one laying around.
Ask me if you have any questions :)
The printable case I made is available for free here:

Parts:
CF to microSD Adapter:
CF Upgrade Card:
Shell replacement (optional):
Edit/Update:
I made a dock for it, that works with the charging/sync cable and fits my case.
Here are the print files for the dock:

Edit/Update 2:
I now also made a storage/travel box you can 3D-print available to download here:

Look at my post on the box here for details:
Do you own some calipers? If yes you could measure the thickness. If it’s as thick as the 5G (30GB, which is the thinnest of the 5th gen), then I don’t see a reason why it shouldn’t work. And if you „have nothing to loose“ I would suggest just opening up your iPod and have a look at the internals. This way you can compare the different cf cards and look for one that has the same connector as your iPod. There are many on AliExpress you could choose from. Pretty sure that can be done somehow :)
I’m waiting on the tools to open it as I also have to replace the battery. I’ll see then what can be done.
I’ll keep my fingers crossed! When everything arrived and you need further help, feel free to ask :)
Thank you.
