I don't think there will be any consequences of importance, for a different, simple reason: people generally resist changing their worldview and will do mental gymnastics to preserve it.
Once the "chemical experiment" escapes its petri-dish and replicates in the laboratory's drain, taking over whole beach resorts and a third of the Pacific ocean, people will rethink!
I think it's pretty optimistic (? or pessimistic) to assume that the "chemical experiment" would have a chance in hell against the bacterial super-predators that have spent billions of years evolving to adapt to this environment.
