Increasingly happy/sad banknote portraits

As far as I can tell, the Queen looks about the same on every banknote apart from ageing. Obviously you don't all have the Queen on your money. It seems to me that the bigger denomination note one receives, regardless of the actual size of one's currency unit, the better it is, although not so much for spending it.

Therefore, the Queen or whoever is depicted on the front of the banknote should look miserable in the lowest denomination, then advance through neutral, smiling, laughing, laughing hysterically, falling off her chair and finally rolling on the floor as the relative value of the note increases. In the meantime, the reverse of the note should depict figures going the other way, perhaps starting with a wedding and ending with a funeral or something, and the colours on each side of the note should reflect the moods accordingly.
