James,
Another idea, a couple of years ago Prince Charles was an advocate of forming a Sikh Regiment in the British Army. The Sikh community resident in the U.K. seemed very positive about this and officials reckoned they would have no problem forming at least a Bn. However the PC types shot it down, no regiments to be based on religion (hmmm, seem to recall a regiment called the Cameronians (Scottish Rifles) were formed originally from Convenanters).

Maybe, as King and post TDM, he gets his way, perhaps a company at first, then maybe The Sikh Guards ?
FWIW approximately 350,000 identified themselves as Sikhs in the 2001 UK Census.
