Yes, but we're only testing levelDB and we couldn't assure that it won't produce unintentional consensus forks with other databases behind the whatever db-agnostic interface. I believe Bitcoin Core should officially support only one database at a time. And if that is to change in the future, I don't think it should be before a storage-agnostic libconsensus is encapsulated (and after that there will still be risks and costs in officially supporting several several databases simultaneously). As has been said, these kind of experiments are welcomed outside of bitcoin/master though.
