don't necessarily take my word for it but that looks feasible. both
wiring and arrangement

Are you using the default BMS shipped with the DeWalt packs?

If you are, I would advise against your blue wires; they will connect
the multiple BMS's in parallel, and the BMSs may not work well when
directly connected to another BMS.

One BMS may not be enough for several packs in parallel; it will
probably try to limit the current to the safe value for one pack, and
if you remove the current-limiting connections, you may impair other
functions of the BMS.

I would recommend just using the red wires in your drawing and
skipping the blue wires. You could also connect the three middle red
wires together. That way, you'll have longer strings of cells in
parallel, instead of every single cell in parallel.
