Not with BDR between 9.4 and 9.5, no, as there will not be a 9.5 version of
BDR. It'll be skipping straight to 9.6.
pglogical, a simplified and streamlined version of the logical replication
facilities used in BDR, can replicate from 9.4 to 9.5 (or to/from any other
combo of verisons 9.4+). It doesn't support multimaster or DDL replication
like BDR does, though.
You can also look into Londiste and Slony-I.
