As you probably have already guessed if you're following the Japanese scans, the reason Luffy's fruit can be projected is because it's a Zoan.

The reason for this is that the manga said that Zoan have their own personality (which could overwhelm the user if their will isn't strong enough) and so I interpreted that this implies also a spirit/soul within!

(Thus, in the second pic, the mini swirly sun over the sleeping Danny, Merry and Sunny is Nika, who's bewildered by the mere concept of staying still and resting. You should move and have fun!!)

Other spoilery plot things include:

Usopp never deflected at Water 7 (there was still angst about the physical death of the Merry, but having her literal spirit hanging out with and scolding you if you were spiraling helped immensely);

Franky's personality (since he's one of his creators) rubbed off Sunny, so he's prone to join him in his dances and screaming "SUUUUUPEEEERRR!";

Danny gives off passive harmless ectoplasm radiations (moreover when he's in ghost form) that the Merry feed on when she's a full ghost and so doesn't need any active recharge;

because of his high metabolism, Danny has to eat either a lot (not Luffy-levels) or food choke-packed of nutrients. They also notice that the rawer the meat, the less Danny needs to eat (since it has higher content of non-degraded ectoplasm);

As I was writing the previous point, a thought occurred to me: could this also be a Ghost Hunger AU where Danny also feeds on emotions? 🤔 Let's keep it on maybe, because with Luffy around it would be like a nuclear reactor to feed on. No, I changed mind again, it's a YES, because there's no Ambient Ectoplasm in the One Piece world (contrary to what I headcanon Amity Park), so the only way for Danny to survive at all would be to stay on Luffy's side almost constantly.

And this leads me to the timeskip separation: because of the battle with Kizaru and the Pacifistas, and consequent use of 1-2 Wails, Danny has to retreat to his Core (first time ever happened), causing panic and forcing Luffy to stash it in the ribbon of his hat due to the heat of the battle (and so be separated along with him).

Danny stays unconscious two whole arcs, until Luffy is about to die of poison on Level 5 of Impel Down. He still hasn't enough energy to manifest outside his Core, but he gives his Captain as much as he could to keep him alive until the Okamas find and save them; he continues to do so even during the Hormone Treatment, having received a boost from Bon Kure and the others' emotional cheering.

After a short rest (he fainted) made during the escape, Danny wakes up again at Luffy's Conqueror Haki shout and given how much death and despair there's in the air, he's able to manifest again and speed up the rescue.

Who lives and who dies? No clue, but given my bleeding heart, Ace Lives, but not without grave injuries for the three of them (maybe so much that Danny ends again into his Core).

I just realized that this could end with Danny adopted officially into the ASL (Luffy had already started the process)... Our boy Danny is so Adoptable™ LMAO

Sabo regains his memories at the news of the close call and hijacks any mode of transportation to reach the trio. Two years timeskip happen with quartet bonding and training, then into the New World We Go!
