Passthrough charging question

I'm trying to design a passthrough charging system for my rpi4b which requires 5v 3a max. I assume it means the regulator needs to handle 6a output if it handles the lipo charger too.
I drew out a schematic with power transistors for control, but I'm not sure I set it up correctly.
Will this schematic safely charge and discharge the lipo batteries depending on (+)in?
