Bitcask doesn't have such interface like hooking anything. As of internal data structure of Riak CS built on top of Riak, bitcask keys don't correspond simply to leveldb key. Say, things like this cannot happen: "all tombstones of blocks of this object were collected and space were reclaimed by merged, so I'm gonna officially hit S3 interface to delete that object". This is because blocks are distributed all across the cluster.
I'd rather recommend to make up a simple cron job that walks over objects and see timestamp and hit CS API to delete them when they're old, or wait for lifecycle API gets implemented.
