Looking for "more unit advancements" addon

[ExVault]

For single player campaigns. For standard units.
Like this - http://units.wesnoth.org/1.6/C/era_ascension.html but its era and addon is outdated.
I found it rather simple to create new units by playing with "Battle for Wesnoth\data\core\units" files.
Maybe someone already made it and I just fail to find?

Look at Legend of the Invincibles. Huge expansion of advancement options.

Try Dugi's RPG AMLA Era, though it's only on 1.10. It's the same author as Legend of Invincibles.

With that unit tree you posted the link for I would spam walking corpses and hog all the kills for them without question
