Boss Tweed... Yes a Multi-Unit would be another good thing to have but this unit is large for an insect and details are lost as it is... IF made smaller for a swarm, the details would be lost to extreme with such Tiny units.
I am sure someone will Tackle the issues and try to make a Multi-Unit of small Hornets...and I wish them Luck with the End Result
... I suppose three or four larger units could be placed for a Multi-Unit with good results if time is taken to do a good job.
Personally, I am behind in Units I need to make and much more work than I can say here but I do agree that a Multi-Unit of Hornets would be Cool
