Sadly there is no rushing desulphation/separator separation. The only thing that would help is if you focus only on the 2 worst batteries then use the car short distances once the 2 baddies are up to snuff. Or if you have access to more than (1) 12v car battery charger, beg a neighbor to borrow one for about a week.
Take care because those batteries are easy to get inbalanced (as you have seen 1st hand).
This means you probably do not want to fully charge using the onboard charger for at least a month because it will overcharge the snot out of your good batteries in an inbalaced string and AGMs you don't want to do that.
What I have done to get around that (and now that I have good batteries), is I monitor how far I drive and how much charging is needed for a given driving distance, I then either monitor voltage on each battery and kill the charger by unplugging so none go above about 15v (or now 7.2v for gel) or I set a wind up timer that kills it after a specific amount of time.
Generally my car requires 75ahr for every 25 FLAT miles traveled (with few stops) depending on my tire pressure and how far I coast before stopping, you know your charge rate. In your case it should be about 60ahr per 25 miles (an ammeter can tell you how much juice it takes) You take the number of amp hours used and multiply by about 1.5 then divide by the charge rate of your charger to get approx time on your big charger (give or take).
Good Luck
