Bagan isn't possible because he has nowhere near the marquee value of established monsters like Anguirus, MechaGodzilla, Gigan, and pretty much every monster that has actually appeared in a film. Bagan was a failed concept, and an early prototype for Battra, Destoroyah, and Desghidorah. Toho probably doesn't even know what he is anymore. Just because the fanbase worships Bagan for some reason doesn't mean he has a chance of getting in. If Legendary wants to purchase the rights to more Toho kaiju, Bagan won't even be on the list of kaiju that Toho offers, and I doubt that anyone from Legendary would even consider Bagan.

Ghost Godzilla isn't possible because there's no way he could fit in the Legendary universe. It would introduce a completely random supernatural fantasy element to a universe that is more grounded and reliant on science to explain its monsters. There is no chance that the skeleton from the opening of G14 will spawn Ghost Godzilla. I'm sorry, and I know this will sound mean, but that would be ridiculous by the standards of the Legendary series. Toho wouldn't even let Legendary use Ghost Godzilla, for the same reasons as Bagan. Toho doesn't see their scrapped kaiju as marketable, and is very selective with which kaiju other companies get the license to.

The most we will ever see Bagan or Ghost Godzilla ever appear in are toys and video games. They had their chance (several in Bagan's case), and Toho decided not to use them in a movie. They were repackaged and used to create different kaiju. Bagan and Ghost Godzilla aren't going to appear in a movie, especially one made by Legendary. I know the fanbase is fascinated by them, but I'm sure Toho doesn't share that enthusiasm.
