Mauro: I like your idea of starting from an empty string. Neat.
As a Java/JavaScript programmer I object to calling it a null string.
I suppose you mean an empty string.
seeds = [""];
I think that the modification rules should be harvested from the VM by a good program that can maximize their probability, not guessed. This should come after the study of source selection patterns, because having at least some credible source-target pairs will help a lot in harvesting the rules.
There is a lot to study and experiment.
