No, as the wms-spec says you have to call a WMS with one ore more
layer-names MapServer has to know the the layer-names (and it does not
make a capabilities call). So you have to write down all names behind
"wms_name".

Perhaps you coud try to load the remote layers in one qgis-layer and
export the layer to a mapfile. You have to check the
'experimantal'-checkbox in newer versions of qgis to see the
MapServer-Plug, It's name sth. like RT_Mapserver..
