Please don't reply off line. I, too, would be interested in the responses to this question. You might contact Andrew Morrough who has worked extensively on the Cappella dei Principe. I believe he is still in Wash, D.C at CASVA at the National Gallery. If he's not there, they can certainly tell you how to locate him.
