I'd say get a spare MSD (any gb higher than 4), get the underprivileged pack (.xyz--google it), format the MSD as fat32, put the unzipped AIO files on the MSD, boot to hekate 5.1.1., launch atmos/pie-rat (
) shop (modified atmos), wages&salary.
The reason I say to do that, is so you have an idea that it: works, to see which files are similar on your main MSD (so you can move/merge/yada yada necessary folders), and have a backup that'll run Edizon (seeing as game saves are on the nand--you can edit your files, yada blah blah).
I think you'll be okay; I have done the most ssa shit (accidentally superbowl caught a Switch, managed to update to 9.1, added FS/ES patches to atmos, and moved right along with life), among other things.
I don't know what you do or care about, but most of the programs I use are fine; Edizon started getting weird because the hid-mitm wasn't working properly, but I just used a different MSD and I'm back to not-grinding for digi-money.
TL; DR, ate a sandwich:
Google underprivileged pack, yes, not really with the AIO, 9.1 is still cool, but a new update will be here soon, so if you don't have the exfat drivers, now is a good time to get the update before you have to wait for authors to update their work.
