More Croaks With Kithguard?

Idle though passing through my head. We know that Kithguard are the next Troll faction. Affectionately nick-named 'Nam Trolls for their dieselpunk jungle warfare aesthetic, they operate in hot and humid jungles. This made me wonder if they'd get an auxiliary expansion like the Firetongue Cadre, and we would see another tribe of Croaks hop onto the battlefield. Thoughts?
