Not really. The Confederate Army was plagued by desertion. That's what happens when rich slave owners rely on the loyalty of poor farmers who need to be home feeding their families. The South was doomed from the start. Here in Virginia, we are still fighting that battle. From this weekend...
Poor farmer's wives were as good a field hand as their husbands, more often than not, and the majority of farms were small.
Eliminate the blockades, which were essential to the Union war effort, and the war would have changed. There was plenty of cotton, all wanted on world markets, which could have been traded for much of what the South needed, and not only for the war effort. Tobacco was also at a premium. Trade policy was part of the reason for secession in the first place.
Had the Virginia sailed that night, and sunk or forced the blockading ships to withdraw before the Monitor arrived, that blockade might have been broken, and others would have followed.
