Another missing leader for consideration:
Joseph B. Kershaw
http://en.wikipedia.org/wiki/Joseph_B._Kershaw
Kershaw commanded a superb bridage of South Carolinians in the Army of Northern VA. through 1863. After Longstreet got rid of Lafayette Mclaws, Kershaw was promoted to division command and served at this level for the rest of the war. There isn't a ton of personal evidence out there about Kershaw, but if the performance of his troops is any indication of his leadership ability, then he would get pretty good ratings. This would fall under the "what if" category, but IMHO Kershaw would have had a good chance of being promoted earlier if some other I Corps officers had been injured or removed sooner.
Some highlights as a Brigade commander under Mclaws:
Antietam - Kershaw delivers a solid counterattack
Fredricksburg - Kershaw fights off the last two Federal attacks on Marye's Heights
Gettysburg - Kershaw's brigade is as tough as nails in its assault, taking on a number of units from the Federal II and III Corps.
Division Commander:
The Wilderness - Helped push back the Federals in Longstreet's counterattack
I would recommend 3/3/2 as a division commander....maybe the "Strong_Morale" for "battle hardened individuals" if you want to add some more flavor.
