If it were me, I'd probably just ignore the check-engine light :-)

But I wonder if you could wind a set of 8 iron-core electromagnets to be
the same inductance as a fuel injector, and then have the LPG system cut
over to the bank of "dummy" injectors. The fact that they don't have a
moving pintle might affect the waveform a bit, but I bet it wouldn't be
enough to trip the computer. It would add a lot of complexity since you
would have to put in 8 relays to switch over from the real injectors to
the dummies, intstead of a single relay to cut in the resistor on the
common side.
