The fraction would work though wouldn't it. Richard 1/3 III
I can see it now:
Richard 1/3 III Buggered at Bosworth....
...or would they give up the franchise so quickly? Perhaps they would paint the Ricardians as Necromancers and raise Richard 1/3 from the grave beneath the car park in a midnight ritual which resulted in a zombie apocalypse in Leicester resulting in:
Richard 1/3 IV Zombie Crookback Terror.....but we're getting way off track now...
