For anyone coming late to the party and unable to find the recovery image to properly repartition your Nook Tablet, I may have some useful information. I was unable to find a version of the recovery that allowed for repartitioning, so I took a few days to look around at what options were available. I settled on just manually repartitioning.
**DISCLAIMER**
I'm a mechanical engineer, not a developer. Perform any of this at your own risk. I'm not responsible for bricked devices. This is only tested on the NT 16GB as that's all I have.
UNLESS YOU BACKUP YOUR DATA PARTITION, THIS PROCESS WILL WIPE IT COMPLETELY. It completely obliterates the last 4 partitions and rebuilds them, so be warned.
So, to start off, I wanted about 2GB of /system to match what @
chrmhoffman's custom recovery did. Thanks to @
grantd, we were given that earlier in the thread
here. Using this partitioning scheme, a bootable CWM SD card (so I could use parted instead of sgdisk, because I'm a wimp and like directions), and the instructions
here, I kind of halfway cobbled together a solution that seems to work. At least my NT boots. And has GApps. So there's that?
On to the process:
1. Boot NT into CWM recovery on the SD card
2. Through the CWM menu on the device, unmount the /cache partition. You may need to unmount another as well, but on mine, only /cache was mounted initially.
3. Execute the following commands (commands are
red and bolded, the rest is output).
4. Once you're satisfied with your partition table, exit ADB and reboot the device into your emmc recovery. I'll assume people are using later versions of TWRP at this point.
5. Inside TWRP, go to "Wipe" > "Advanced Wipe" and check "System". Then tap "Repair or Change Filesystem" > "Change File System" > "EXT4". Do this for Cache and Data as well. The parted commands below only generate ext3 filesystems, and I was too lazy to figure out how to do it myself in parted and/or sgdisk.
6. Flash your ROM and GApps package and have a ball with your newly invigorated Nook Tablet. We also get some bonus device data storage out of this, since userdata and media are merged into a single partition. Yay!
**Note: For some reason, the AOSP 7.1 ROM located in the
Notre Dame Box kept resizing the system partition to ~644MB or thereabouts... I have no idea why. I had to go for lnos_acclaim-ota-NJH47F.180713, at which point I had my full storage available in /system, which I used to install GApps Pico

Error: The backup GPT table is not at the end of the disk, as it should be.
This might mean that another operating system believes the disk is smaller.
Fix, by moving the backup to the end (and removing the old backup)?

So essentially what we're doing here is nuking the last 4 partitions back to and including /system, rebuilding /system with 2GB-ish of space, then allocating the rest to /cache and /data.
