Not directly. INSERT/UPDATE/DELETE returning always return plain hashes
and not model instances.

This will probably be an easy work around:
Model.returning.multi_insert(hashes).map{|h| Model.call(h)}

However, note that Model.new creates an instance not yet saved to the
database. If you want a instance for which there is already a database
row, use Model.call/Model.load. However, note that Model.call/Model.load
do not do any typecasting, they use the provided hash directly as the
values for the instance.
