I actually think that cfengine do this the right way, since the edit
operation and the copy operation has very different criterias to
succeed.

If you split it up and have:

  copy templates from policy host
  editfiles / InsertFile on the client side with the logic in cfengine


control:

  masterfiles = ( /var/cfengine/masterfiles )
  inputs      = ( /var/cfengine/inputs )


# this is just one file, you will probably have a copy operation
# that copies more files at the time

copy:
  /path/to/template.in
    dest=$($masterfiles)/template.in
    server=$(policyhost);
 

editfiles:
  { /path/to/result.file
    EmptyEntireFilePlease
    InsertFile $(masterfiles)/template.in
    ReplaceAll "TEMPLATE_VALUE" With "$(host_value);
  }
