I would love to see,
1. Roman Signifier, with his helmet having the lion's head and skin draped over it and around his shoulders (moulded plastic), holding his signum.
2. Roman Emperor, with his wreath upon his head, possibly a scroll in hand.
3. Monk, with robe with hood down and distinctive monk hairpiece, carrying a 'wee willie winkie' candle holder or candleabra and book.
4. Monk, with robe and hood up, carrying cross and or chalice or quill and book/parchment.
