Replace the inrush current limiting (ICL) circuit
Less power. Current circuit wastes power to keep the NTCs hot.
If the main pack is disconnected from DC-DC, the HV caps will discharge, but the NTCs will still be hot for a while. When the main pack is reconnected, the ICL will not work because it’s already hot.
The NTCs probably won’t share the load evenly, which risks damaging them.

Switch to a 24V low voltage system?
I think a lot of the 12 V components we use (relays, etc) usually have 24 V variants that draw less current. This would reduce the losses from parasitic resistance.
