Not an alarm guy and also currently installing a new panel ELK from old Napco. Did you already buy the Smokes? If not, can't he use 2 wire smokes thus then running them in series and end in a loop back at the panel? I am using the System Sensor Cosmo smoke/CO2 detectors. Which uses the module so panel thinks its a 4 wire smoke zone anyway and can be used on any zone vs the limited 2 zone.
I think he already has them all but even if he did, 2-wire smokes do not cost that much. So he could replace them all without breaking the bank.
Your idea would work but they are not technically in series. They are still wired parallel but in a daisy chain fashion. As an example, it would start with using the white/green to the detector, then the red/black from there back to the panel, which would tie directly to the white/green of the next detector, then red/black back again from there to the next again. Until we reach the final detector where the EOL is wired (or at the panel on the red/black back from the last one). Only the 1st white/green is connected to the alarm panel.
