Question about the built in fonts...5.18.2 OA3 and 5.18.3 PW5

Both are jailbroken via Adbreak.

I'd like to remove or hide some of the built in fonts like Baskervlle, Futura, etc. as I do not like them and will never use them. Is this possible?

I'd basically like to prune the list so I only see fonts I will actually use...such as Ember, maybe Bookerly, Helvetica and then whatever fonts I add myself.

Built-in fonts are kept inside read-only squashfs image that's being mounted into particular file path.
So to edit that you would need the tools and the knowledge how to re-create new squashfs image with only desired subset of font files.

Or you can simply ignore them and not risk bricking 2 Kindle models that basically can't be un-bricked

Oasis 3 can't even be disassembled without damaging it and there is no point in opening up PW5 because its motherboard doesn't even have serial connection pads.
