Are Legendary models an analog for their non-legendary counterparts?
In other words, can Legendary Abraham Lincoln utilize the Secret Service Theme Posse or can he only use the generic Union Faction or Manifest Destiny Theme Posses?
Additionally, can non-Boss Legendary units be recruited into a Theme Posse led by a non-Legendary Boss?
The Tombstone Theme posse for Wyatt Earp seems to indicate one way while other Theme Posse builds muddy the waters (Looking at Morgan Earp specifically here).
Any assistance is greatly appreciated.
