After some thoughts I personnly doubt I will ever buy a non-safe chemistry li-ion D-cell. Even if it is protected, I really much prefer that the cell itselft is safe and not a grenade.
That said, if you are ready to accept the risk. I'm not sure why you say balancing is so critical?? AFAIK balancing is usefull to ensure you are not over-charging a cell in the case you charge a whole pack. Which is not the case here, if you charge them one by one.
Also, balancing is usefull to ensure you will not over-discharge a cell when used in serie. In that case, balancing alone is not enough, you also want the cells to be well matched. A perfectly balanced pack that do not have well-matched cells can also lead to an over-discharge cell (the one that has the least capacity will run empty before the others).
If you charge your cells one by one one a similar charger, they should be very well balanced at the beginning of the discharge. How well they will remain balanced at the end of the discharge depends on well the cells are matched.
At last, if these cells are protected, the PTC should prevent any cell from going over-charged/over-discharged.

then there's balancing which is more important the larger the battery and the larger the load.
