I believe its possible and that is part of how they "rebuild" packs along with a "reconditioning" of the cells. But you need the right batteries, tools and knowledge to do it right.

"just D cell batteries" - no, they're not JUST "D" cell batteries.
They are the best, most expensive "D" cell battery ever made. Nothing available as a consumer "D" cell is even remotely close. These individual cells are capable of 100A of discharge and 50A of charge currents. Try that with an Eneloop "D" cell (a great consumer NiMH battery), and it will explode on charge and drop to 0V on discharge.
When the Panasonic versions of these cells were available for purchase for industrial applications, they were $20 each. There's 250 cells in them.
Per Hippo's comments, no. CELLS can't be replaced in any reasonable way; however, reconditioning and replacing entire 5 cell subpacks is very viable. The trick is testing and identifying the good and bad from the 50 subpacks.
