I couldn't quite parse that last paragraph ;-) but if you can't do a
nixos-rebuild, then here is a very hacky way to add a path to the firmware
search path:

$ find $(nix-store -qR /var/run/current-system/ | grep udev-rules) \
  | grep 00-path
/nix/store/08n14c4v8nnz4zi0jwl763r840p4kszj-udev-rules/00-path.rules

and edit the line ENV{FIRMWARE_DIRS}=... in that file.
