Why not just use the --go-live option for MRIT and _put_ the data in collectionB? Note this only works for Solr indexes that are hosted on HDFS...
If your Solr collections are not on HDFS, then it's the same process as I outlined. You create collectionB and copy things "to the right place" after MRIT is done then alias, switching back and forth as necessary. The point is that you have two collections, the one currently serving queries and the one getting indexed to. You go through whatever process you need to completely rebuild the offline colleciton's index, then alias.
