Jamie, there is no way of knowing accurately how many Louisianians who served in the Confederate army have no wartime record of that service. In another lifetime, when I was working at the Louisiana State Archives, I recognized the need to update Booth's books due to the thousands of missing, inaccurate, and incomplete entries in them. While Booth gets credit for the volumes, his predecessors actually did all of the work that went into them. They had limited access to existing muster rolls, sick lists, &c., while they were compiling information on the state's Confederates. I proposed a new roster project similar to that put out by North Carolina, but there simply was not enough interest nor enough funds at the time to initiate it. A good example of how Booth's books are incomplete is the fact that the LSU Archives holds some muster rolls for the 8th Louisiana Cavalry Regiment which were made out right at the end of the war. To my knowledge, they are the only existing muster rolls for that regiment, and they were not available to the men compiling the roster. Thus, the only men of the 8th Cavalry who appear in Booth are those who were paroled at the end of the war and whose names appear on parole lists. There are dozens of similar muster rolls around the country. Additionally there are other documents that provide information on Louisiana Confederates not found in Booth or expanding upon what is in Booth. All of this is a long, convoluted way of saying no one has attempted to catalog or quantify these "missing" Louisiana Confederates.
