What are your thoughts?

You're almost 100% on the ball, but there are some things that you have overlooked.

Styx - The River of Hatred, this is the river that circles the Underworld seven times.

Archeon - The River of Pain, it's the river that Charon, also known as the Ferryman, rows the Souls of the Departed over to the Underworld.

Lethe - The River of Forgetfulness, is associated with Lethe, Goddess of Forgetfulness. It's also said to be associated with Hypnos the God of Sleep. The Sleeping Curse is out of the question because most of the characters who have journeyed to the Underworld have been under the Curse, but a Forgetfulness Curse could cause them problems.

Phlegethon - The River of Fire, this river is said to lead to the depths of Tartarus. I'm 50/50 with the theory that this is where they will find Hook because according to Greek Mythology, Tartarus is not considered as part of the Underworld, it's described as being far beneath it. It's also known as the dungeon where Zeus cast the Titans, according to a visitor to the Underworld known as Odysseus although he did not see them himself, he mentions some of the people within the Underworld receiving punishment for their sins. However there is another place in the Underworld where they may find him.

Cocytus - The River of Wailing, the river of grief and sorrow. It flows directly into Archeon.

Oceanus - The River that encircles the World. It marks the east edge of the Underworld, whereas Erebos is West of the Mortal World. Erebos is the name of the Underworld itself (like Misthaven is the name of the Enchanted Forest), it's also the part of Oceanus where the dead pass immediately after dying, and is sometimes used interchangeably with Tartarus. So basically Oceanus exists throughout all the Magical Realms and the Real World, but when somebody dies Erebos immediately sends their soul to Archeon.

Like I said there is another place in the Underworld that the characters are likely to find Hook:

Fields of Asphodel - This is basically the Underworld version of Storybrooke. In Greek Mythology the Asphodel Meadows was a place for ordinary or indifferent souls who did not commit any significant crimes, but also did not achieve any greatness that would warrant them being admitted to the Elysian Fields. This is basically where Henry Mills Sr. has just gone, and another part of the characters mission, to help the Souls of the Departed out of Asphodel and into Elysium.

Fields of Punishment - The Fields of Punishment is a place for those who had created havoc on the world and committed crimes specifically against the gods. Hades himself would make the individual's punishment of eternal suffering based on their specific crime. During his pirating days Hook did cause a lot of havoc in trying to get his revenge, during which he committed a crime against a god, he tried to attack Poseidon, the God of the Seas. So this is another most likely place where Hook will be found because when Emma summoned his spirit with the Magic Ale of DunBroch it looked like he was in constant pain. The only problem is I can't find anything in any Greek Mythology about the location of the Fields of Punishment.

The reason behind this theory is because Tartarus is used as a Dungeon and from what I've read any punishment received there is given on a regular basis, but someone sent to the Fields of Punishment experience eternal suffering.
