On the ds, the threads have just disappeared into the nipple and on the nds there is 1.5-2mm thread sticking out (12mm nipple, I'm guessing there is 8-9 turns of positive thread engagement on the nds).
If needed, I will disassemble and re-re-build using the nds spokes on the ds and buy new longer spokes for the nds.
By using longer DT Swiss nipples, like the 14 or the 16 mm version, you lower the thread grip by 1 or 2 mm. Cheaper and faster than swapping and buying new spokes.
IMHO, if the wheel is stable regarding spoke windup, then it should work in its present state. In theory, 3 turns of engagement gives enough strength. Of course a good margin is advisable for bicycle wheels, but it sounds like you have this margin. Just check the wheels occasionally when first using them.
