I see the advantage of 6V over 12V simply as price per usable AHr capacity for X amount of probable life in a form factor that is readily available. Getting the same type of individual cell capacity of a GC but in a single 12V package has always been quite a bit more expensive option in my battery power solutions for projects.
Basically the idea of using 2V individual cells boils down to what impact those external connections might make. My rule of thumb in every series configuration I've done is that the connection between cells in series must be identical and that would be difficult if the cells had to be in different locations. I wouldn't recommend a long distance between GC batteries either ... if you must store in multiple locations I'd recommend each location to have same capacity and final voltage so they connect in parallel.
