How can it not happen? MechaGodzilla is one of Toho's Big Five alongside Godzilla, Rodan, Mothra and King Ghidorah, that makes it a popular character in the entire franchise because it's in all previous eras of the series.

Having the other four appear in one film while this particular character appearing in none makes absolutely no sense.

On top of that, Legendary Pictures' goal is not really realism, it's actually grounded believably, or else Godzilla (2014) would not have been made, as that film is not even close to reality, the purpose of Legendary's Godzilla films is to explain "What if these monsters actually existed?" with the monsters themselves designed in ways in which the way they live makes a lot of sense (hence why Godzilla has gills in this universe), and their backstories told in ways in which is very well believable.

With that said, MechaGodzilla in the Legendary era can be made possible. If Legendary Pictures buys the rights to use MechaGodzilla in their Godzilla films, like they did with Rodan, Mothra and King Ghidorah, then it would be given a new origin that would very well fit the grounded cinematic universe Legendary Pictures intends to create.
