Morgan doesn't want to have separate trees.  Like in civ3, if you play 
Japanese, you get Samurai unit instead of Knight, but this unit is 
available at the same point in tech tree (Chivalry).

An approximation is possible in the current ruleset structure, when you
can create a special dead-end offshot tech.  In the above example you'd
have a special tech Samurai Code (Bushido) which requires common Chivalry
and nation specific root tech.
