Strange requirement, but you can tag nodes with a shard allocation filter http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/index-modules-allocation.html#index-modules-allocation
and then you can create an index with replica level 0 that will be created only on the tagged nodes. After that you can remove the allocation filter and increase replica level. Do not forget to check if index recovery and restarting ES will work as expected.
