New Copium: after 5.3 update, Capitano passed "Albedo's test"
There's a pratice to test if a Character has a playable model by using the "Albedo's test". This test consists of using Albedo's skill on a character during a quest / dialogue to see if it has a playable model: if the character is not lifted / fall by the platform, it means it has a playable model. If he's lifted and remain in the air, it means he has an NPC model.
Every other Fatui (including Scara's old model, except Signora that cannot be tested because in every scene where is present multiplayer is not active) passed the test.
In 5.1 they did this test with Capitano and he did NOT pass (he remained in the air).
BUT
They've tested him again after 5.3 version update and HE DID PASS! It seems like his model and collisions were slightly adjusted in 5.3 to match that of other playable characters... Of course, that doesn't guarantee that Capitano will be playable, but from what I've understand it means that Capitano's model could be 100% suitable for in-game mechanics and exploration.

EDIT: "ペェモン -最高の非常食-" said that there are two possible explaination for this:
- Albedo's skill physics was changed (which would be strange since this thing worked for years)
- Capitano is playable
