Hi @AmitKannaujiya, I think that, after merging your PR #3 this is gonna be definitely possible, since phpredis provides a drop-in replacement for RedisCluster.
The only problem I foresee is testing, because we would have to create a redis cluster in travis using docker. Let me know if you have ideas to make it work.
