Some starting points:http://en.wikipedia.org/wiki/Gaius_Musonius_Rufus
"The Suda states that there are "speeches about philosophy bearing his name," and mentions letters to Apollonius of Tyana. The letters that survive are certainly not authentic. It is unknown whether Musonius wrote anything for publication. His philosophical opinions were collected by two of his students. One collection of Discourses, by a certain Lucius, form the basis of the 21 lengthy extracts preserved by Stobaeus. A second collection was compiled by one Pollio; it has been lost, but some fragments survive in quotations by later writers."
"Apollonius of Tyana... was a Greek Neopythagorean philosopher from the town of Tyana in the Roman province of Cappadocia in Asia Minor...compared to Jesus of Nazareth by pagans in the fourth century and by various popular writers in modern times."
On Musonius Rufus: A Brief Essay (1999) Richard Carrier http://www.infidels.org/library/modern/richard_carrier/musonius.html
"Since this man deserves far more publicity than he has ever gotten in the modern age, I have written this short essay. He exemplifies the sort of man who should have been venerated and made the founder of a world religion, but was not, yet he was the moral superior in my opinion to Jesus--not perfect, but admirable within the context of his own day."

These touch the surface and even so, perhaps one can see that any connection between one Rufus and the other would provide an interesting context for a history of Alexander.
The cognomen Rufus crops up in some interesting places. My approach in trying to understand how beliefs develop over centuries includes looking closely at the genealogy of the bearers, because such transmission requires, I think, an institution to carry it and a dynasty can be such.
