Okay... I thought about it some more...
I want to be able to pokegen.
I want my 3DS to autoboot into GWemuNAND when I press the power button using arm9loaderhax. But I also want the option to hold a button and load a boot manager during startup with the following selections:
1) Gateway emuNAND (w/redcart) <--- what it would normally autoboot into
2) Gateway emuNAND CLASSIC (so I can use Bluecart, DSTwo, Sky3DS, retail carts)
3) Whatever NAND I need so I can dump all my emuNAND data using FBI (do I need this?)
4) sysNAND (which I barely expect to ever use, but just in case)
Title manager doesn't cut it on 128GB. It works for installing .CIA's, but not so well for dumping and restoring savedata. I need savedata dumping/restore for pokegenning and backing up game progress. GWemuNAND works fine for installing .CIA''s and using redcart, but I also like using bluecart and DSTwo, and even Sky3DS. I like using the Sky3DS with Pokemon XYORAS because of Powersaves. Redcart cheats are nice, but Powersaves Pro is better. But I also want to be able to pokegen using PKHeX.
Does this help? I'm not interested in a free CFW. I already have the GW. I just want to skip the browser load for GW Menu or having to go through settings entrypoint.
EDIT:
I like using the DSTwo to save mSD space. This way I can DL NES, SNES, etc. ROMs onto the DSTwo instead of installing Virtual Console .CIA's (except for new Pokemon Red, Blue, Green which HAS to be an eShop DL). I like Bluecart because it saves space on DSTwo. This way I can have retro games on DSTwo, DS games on Bluecart, and eShop games on Redcart while installing all the .CIA's I want on my mSD.
The Sky3DS is mostly for Powersaves Pro and being able to share games with non-hacked 3DS units for multiplayer/sharing. This way I can use Powersaves on Pokemon, or share my Sky3DS with friends without having to worry about their FW# or not having an extra copy.
Yes, I'm aware that eventually I'll have to upgrade to a Sky3DS+, or a DSTwo+ and I still need to add an N2Elite and get an N3DSXL which I'll then use GW on and keep my O3DSXL just for reasons, I guess. So right now, I'm okay with not being able to play the N3DSXL games. That's kewl. But I'm more than willing to put an O3DSXL to good use...
