If one only does that, yes. But one could also hit the original pretender monster numbers with #restrictedgod, too, which I think removes them from everything but the restricted nation. One could choose a nation value that isn't available in the scenario, and I think they'd be gone. Or at the very least, even if that didn't work, you could change the original ones to something harmless or unavailable or whatever. But I think I tried that before and it seemed to work, IIRC.
