Say, in the context of finding microbial life on Mars (i.e., organisms that evolved from the start with six nucleotides, not just taking current terrestrial organisms and swapping out the nucleic acids and ribosomes).

Translation errors seem like biggest problem, with the current system you have some amount of redundancy where sometimes a single point mutation still gives the same codon but you would lose that with less base pairs per codon
