Can you be specific?
Reading the Church Fathers you will see that Simon Magus is spoken of being in Rome much more than they mention Simon Peter. When Justin Martyr wrote [152 A.D.] his Apology, the sect of the Simonians appears to have been formidable, for he speaks four times of their founder, Simon; and we need not doubt that he identified him with the Simon of the Acts. He states that he was a Samaritan, adding that his birthplace was a village called Gitta; he describes him as a formidable magician, and tells that he came to ROME in the days of Claudius Caesar (45 A.D.), and made such an impression by his magical powers, THAT HE WAS HONORED AS A GOD, a statue being erected to him on the Tiber, between the two bridges, bearing the inscription ‘Simoni deo Sancto’ (i.e., the holy god Simon)" (Dictionary of Christian Biography, Vol. 4, p. 682)
Those are your bones!
I know its a lot, but I would use Acts 10. My Bible (NAB - I hate the translation, but it is well used/worn), identifies the section as "The Inauguration of the Gentile Mission."
As for Simon Magus, yes he was in Rome, as for the bones being his or Simon Peter's, I don't think we will ever agree on that. Arguing further, will do neither of us any good.
Let me know what you think about Acts 10.
