. Also, low Confederate tariff rates will divert most, if not all, of the trade going into Northern ports to Confederate ports (a major reason why the Lincoln Administration decided to oppose secession and go to war in OTL), which means that Confederate tariff revenues will be quite high, even with a low tariff rate.

Rather doubtful since the Union has a MUCH bigger economy. Lower tarrifs help but it does little good to bring goods to New Orleans if the vast majority of the buyers are in places like New York and Philadelphia. That is assuming that a Civil War victory won't balkanize the entire within a decade or two making the area about as peaceful as 11th century Europe, which is quite likely.
