It's true that the height difference seems too big, even for Jean, but this is a manga, not real life. Yes, Isayama is very realistic when it comes to these things, but he admitted that not all things are realistic in this story.

For example, he admitted that a girl of Mikasa's frame and height wouldn't actually weigh 68 kg, it would simply be physically impossible. Kenny is a similar example, being tall but slim, yet he weighed 120 kg. Another example are the warrior cadets, who range between 138 and 146 cm, and yet, the average height for twelve year-olds, both male and female, is 155 cm. AND some of them should be about the same height as Eren and Mikasa by the time they reach 15, which is 170 cm. A 30 cm height difference in three years, even for those on the cusp of puberty is nigh impossible.

In reality, most males don't grow further than 5-7 cm after they reach the age of fifteen, and by the time they're seventeen, they're pretty much done growing. But Eren looks to be at the very least 180 cm, comparing him to Reiner when they're both seated. Manga and anime, in particular, tend to make growth spurts come a little later in life, to clearly identify the teenage protagonists from the adults, and not make them appear too adult-like. Some laws of nature are very clearly being broken in the story because, as I said, it's just a story, so I believe it's very possible that either Connie or Armin are the mystery soldier. It's not guaranteed, of course, but I'm just throwing it out there.
