If they are electrically split .. then for all practical purposes they are separate battery packs.
If they are not electrically split .. it depends on the input to output isolation of the charge in question , some will still be fine with it .. others will not.

It will allow you to do what each IMax B6 can do ... up to 6 cells each .. 4 units x 6 = 24 total 'cells'.
I write 'cells' above ... because each 'cell' could actually be multiple real cells all required to only be in parallel... thus effectively acting like a single 'cell' made up of multiple actual cells.
You previously described 9 packs of 18 cells each pack .. that would require at least 3 units of IMax-B6 per Pack of 18 cells x 9 such packs = 27 total IMax-B6 for all 162 cells... If you aren't electrically splitting them up .. check the Input-Output isolation.

Alternatively if you tried to do the pack in sequential sections using a smaller number of chargers .. that could work .. but is a bit risky .. over time you'll add up a lot of connecting and disconnecting ... it only takes 1 human error or 1 bad connection and then the pack isn't balanced .. and can be an issue if used before the problem is identified... but , so long as no errors are ever made .. sure it can work.
Before selling yourself on a fewer number of sequential charger style system .. think about the amount of time .. both electronics time .. and the amount of human involvement time needed.
