Ok, after toying around with various mods and converting sse nexus mods with the skyrim nx tool, here are a few notes:
- As mentioned by previous posters, the DLCs (dawnguard, hearthfires and dragonborn) .esm can be removed, freeing up your mod slots to 10. So make sure you do that to free up 3 precious slots.
Im not sure about the amiibo mod, would need more instructions on how to free that slot up too.
- The NX tool takes a while to get used to, but it works wonderfully. Take your time and just follow the instructions on the youtube video in post #1.
- Filesize and memory: Small mods like ars metallica and obsidian weathers convert pretty quickly (about 100mb or below) with the tool.
But large mods such as Beyond Bruma, Falskaar and Helgen Reborn will take quite a bit of RAM power and time to convert (at least an hour or more).
So if you're running a potato like me, dont be too ambitious and stick to converting small mods. Or you can just wait for someone to convert them for you on Nexusmods.
- merging mods is quite a PITA (but then i read that it's tricky too even on PC), because the Merge Tool needs to detect a copy of skyrim SE on your laptop before you can run it.
It seems to be a delicate operation as I keep getting errors about merging whenever I try to run it. And not every mod can be merged too. So I gave up on merging entirely.
Would love to see a more straightforward solution sometime in the future.
- And yes USSEP works! (or at least it seems to be working, as I have no idea how to check if its properly installed).
You can't just convert from the normal USSEP patch because it contains some animation file that doesn't work on the switch.
You'll need to retrieve the havokBehaviourPostProcess.exe file from your own copy of Skyrim SE and Skyrim Creation Kit (again another PITA), and a copy of the legacy unofficial skyrim patch (USLEP).

Being able to run mods on a portable skyrim is just goddamn awesome. While I doubt we'll see SKSE support, for the non-hardcore modder there's still a ton of options to explore.
