If you're banned anyway, there's no real reason to use the emuMMC.Haha! So the sysMMC is faster? And there is no need to boot into emuMCC anymore?
Not only does it waste space on your SD card for nothing, it also requires to you to pick everytime what to boot into from hekate whereas you could just auto-boot into sysNAND with Atmosphère from now on.
And yes, the internal MMC is usually faster than the SD card but only slightly (at least in case of the Nintendo Switch).
If that helps, I even went the route to flash my emuMMC onto my sysNAND on my old V1 Switch although it isn't even banned. I realized I almost never booted into the sysNAND anyway, Nintendo's online service is a joke and so there was no real reason for the dualboot setup. Of course I have a NAND backup of my clean NAND just in case.
Btw you definitely should make a NAND backup even if you're banned, before you flash your emuMMC onto your sysNAND because apart from homebrew/CFW the only real other reason for an emuNAND is that there's an additional layer of protection if you manage to break the system somehow.
That is however very unlikely, unless you do something stupid with HacDiskMount or something like that.
tl;dr: Make a NAND backup (just in case), then flash your emuMMC onto your sysNAND and have hekate auto-boot into it with Atmosphère.
If you need assistance with that process, just raise your hand.
