Possible to reroute to a PCB-Version to stack on top of a rapsi 3b+?

Hi JLCPCBMAN! :-)

i was trying to connect a raspi 3b+ underneath your board, made a custom 40-Pin-Cable but having troubles with colors (maybe because of missing shielding).
As you did not provide any source-files for the pcb, might it be possible for you to make a version of the pcb in which you re-route the pin-connector to the raspi so your board can stack on top of a rapsi's regular 40 PIN-Header or provide the source-files to do it on my own?

Kind regards,
André
