The obvious booby trap for the south, beyond the strong possibility that Arkansas, Tennessee, North Carolina and Virginia may not go along with the rest, are the many issues of vital import which were effectively forfeited by the act of secession yet which are desperately important to the south.
1) The territories, none of which went into southern hands OTL.
2) Trade and tariff issues. Now the CSA has to pay its own way and may be in for a bad shock when King Corn turns out to be more influential than King Cotton. People can make clothing last, not bread.
3) Transcontinental railroad. Now the south can't build one on their own for a long time and there's no hope the first will be built near the new border.
4) Fugitive slave act. Not only dead but now the problem starts at the Mason-Dixon line(or further south!) instead of Canada.
The one issue marginally favoring the south...
5) Ol' Man River, aka the Mississippi. Acquired by act of the federal government, the Midwest is going to respond extremely poorly to any limits of access to the river OR new fees charged. This might be a useful bargaining chip for the south except that the north's minimum requirement is going to leave a river running for hundreds of miles in the south as an international waterway and not compromising effectively forfeits the one real bargaining chip.
