A340-500 Merge Overland/Wilco

Hi all,I would like to use the panel for Wilco/Feelthere A340-600 for the Overland A340-500.I know about a merge for the A340-600 where one move the Overland model into the Wilco folder and edit the contactpoints and lights section of the aircraft.cfg.However, how would one do this for the A340-500 since the wilco fleet does not include the -500?Any ideas. I would love to have a fully functional A340-500 in my hangar.
