I hope you don't mind me suddenly butting in here, but I noticed this conversation and I've just found a primary source for this!
Archibald Cameron, writing in 1753 and quoted by Robert Forbes in The Lyon in Mourning, says:
I likewise declare on the word of a dying man that the last time I had the honour to see his Royal Highness, Charles, Prince of Wales, he told me from his own mouth, and bid me assure his friends from him that he was a member of the Church of England.
Archibald could have been mistaken, of course, and he doesn't say anything about the circumstances of Charles's conversion. But at least it was something that people were saying in the 1750s!
