They actually did act as the new elements of harmony, their heroics just wasn't depicted in the show as it focused on the mane six. Their heroics that happened offscreen were referenced though: https://derpibooru.org/2158876?q=toasty+rhino+boi

The fact they are the successors is alluded to many times throughout their appearences. In addition to visually respresenting them in School Raze and Uprooted, they were included with the pillars and the mane six in the final rainbow laser from the elements makes it clear that they are a part of it, the symbolism there is pretty obvious. The fact they are different special is just an extension of the racial parity that the elements have always had, first it was a symbol of the different pony races working together, and now it's symbol of their friendship spreading beyond just ponies.
