As far as I know, you cannot use substitution args inside <rosparam> because roslaunch just parses the complete text using a yaml parser, i.e. no substitutions are done. On the other hand, you cannot create lists using <param .../> so I assume that what you are trying is not possible at the moment. I think that this would be a nice feature to have. Maybe you could open a feature request at https://code.ros.org/trac/ros/.
