You can _do_ that ,sure.But I am not sure what you are trying to get at. RavenDB is a persistent ACID database. Memcached is a cache.
Totally different things and optimization scenarios.

I'm currently running both (actually couchDB as a memcache replacement)
Make sure to look into the aggressively cache part too
