Interesting question, but I think it doesn’t work becasue it’s based upon a flawed premise: that either can be eliminated.
Since there is no single point of failure for either system, so long as there are entities (people, and who knows maybe one day AI) running nodes for Bitcoin and Nostr…and of course market demand for them, they will exist.
