Missionary Ridge Scenario - Available OOB's?

[the reb]

Hello All....

Good golfing weather in South Central PA.....

Anyways.....I would like to do a Missionary Ridge Scenario (or close to it) and was wondering if there is an existing OOB out there that would have the Confederate Army as Bragg as Commander, with the Corps of just Hardee and Breckingridge, etc. Union Army...Grant and Rosecran with Corps of Hooker, Thomas and Sherman, etc.

I never modified a OOB before but if not, I probably could use an existing OOB available and get it closer to history. With that said....any tricks to modifying OOB's.. I might just end up using the Chattanooga OOB and be done with it but thought I would ask....Maybe someone is working on this scenario?

I just finished a Fredericksburg Scenario (Confederate Army) using Salem Church Map that during playback, actually didn't turn out that bad.....

thanks,
