Good suggestions, I would like to include more Italians as well as some figures from other areas such as Scandiniavia, Poland, Spain, Portugal, Switzerland, Denmark etc. Trying to stick to Catholic regions at the moment. In the future if the project is relatively successful/popular I'll be moving onto other regions like Russia, Middle East, etc.
Only thing about these suggestions is that Castruccio and John's references are actually made about 40-50 years after their deaths. I know Hawkwoods memorial is from 1436 when he died in 1394. Maybe Mohatmair has some images in his vast archive, but I may have to make an educated guess at what they may have been equipped with.
