I second this -- do not try a B2B.
Depending on the day you arrive, ALG immigration could be completely full or empty (those twice-a-week MRS/NCE/BOD/LYS/etc seem to never depart or arrive at the same hour...), and the process to get someone to get your boarding pass/go through security is a 30-minute affair at the minimum.
Given that boarding for flights at ALG begins well before departure (I've seen gates open 2 hours before departure), it's best not to do a B2B there.
As a counterpoint though, first-hand experience says that airport officials are bribe-able, so you might be able to do something (under)-handed there...
