Sounds like a serious invitation! If you're ever out my direction, it's 85 miles to the nearest ACW military action at Pichacho Pass. It's located near Pichacho Peak State Park.
A couple of rejoinders on Lee's reorganization. It should not have been as difficult as it sounds. Longstreet's Corps remained the same except for reassignment of Anderson's Division. Three divisions had to be easier to manage than four. The same is true for Ewell's Corps, minus the six-brigade division of A. P. Hill.
As for Hill's Corps, this was essentially his own division plus Anderson's Division and two new brigades. Hill, Harry Heth and Richard H Anderson had been captains in the old army. Dorsey Pender had been a 1st Lieutenant in U S service. All had demonstrated strong leadership skills, so leadership in Hill's new corps was equal to either Longstreet's or Ewell's Corps. Hill's prostate problems became worse after the Gettysburg Campaign, so his health, realtively speaking, shouldn't be an issue, either.
Battalion organizations should have made management in camp and field much easier. Southern artillery was certainly more effective at Gettysburg than it had been in earlier battles such as Malvern Hill and Sharpsburg. This should have been done in the AoT before Johnston's arrival in the winter of 1863-64. Organization (or reorganization, if you will) should have improved Lee's chances in this campaign, not diminished them.
