Holbein and the Princes in the Tower

From AJ Pollard's Richard III and the Princes in the Tower:

Quote:

the idea that Richard of York survived to reappear in Sir Thomas More’s household and there to be painted by Hans Holbein in 1527. Jack Leslau’s disentangling of the iconography and rebus of this painting, whereby he claims to show that the physician John Clements was really Richard of York in disguise, is breathtakingly ingenious. ‘Hans Holbein,’ he concludes, ‘concealed a message for posterity in this group portrait of the More family together with a portrait of Richard, duke of York, thus “proving” that he was alive in 1527 and living under...the protection of Sir Thomas More’. For good measure, Edward V is also said to have survived and to have been disguised as Sir Edward Guildford in another Holbein painting. Furthermore More’s vivid account of the murder of the princes in his History is discovered to have been a ‘smokescreen’.

This was first advanced the year before I was born I guess, just heard of it recently. When I did a search online I found stuff basically either saying "buy the book" or "this guy is a nut burger". I'm wondering if anyone knows more about this and what you think?
