Thanks, I just thought of another idea.
Crusades and all that are probably seen as too controversial when going further than just some loose figures, but maybe they could release a medieval hospital with Hospitaller knights and monks?
It would both honour the Malta factory workers, teach children about medieval healthcare and it would bring some Hospitaller knights too.
There could be several beds for the patients, also a cabinet with various little bottles, herbs and a jar of leeches, two patients, a Hospitaller monk, soldier and knight.
