Sounds fine to me.
Only house rules that i was thinking are ones controlling raiding.
People have different approaches to this and here is what ive been thinking.
Raiding involving, 
pillaging, 
destruction of railways or structures in 
opponents home states only by units 
with a leader.
(Raid like 
Griersons http://en.wikipedia.org/wiki/Grierson%27s_Raid or 
Merrits http://en.wikipedia.org/wiki/The_Burning_Raid )
Raiding involving, 
attack, 
ambush and 
capture of enemy troops, railways or structures in 
opponents home states is allowed by units 
without a leader.
(Raid like 
Stovepipe Johnsons http://en.wikipedia.org/wiki/Newburgh_Raid or 
Gilmors http://en.wikipedia.org/wiki/Gilmor%27s_Raid )
Raiding involving, 
pillaging, 
destruction of railways or structures in 
players home states can be done by units 
without a leader.
I think disputed border states W.Virginia, Kentucky, Missouri, Kansas Territory and Indian Territory should be open to both players as home states regarding raiding.
Raiding (and off course all other) 
river movement in 
enemy owned territory  has to be done with 
naval units.
What do you think? Did i miss something, i typed this of the top of my head so bare with me.
