Calgary already has 5 goalies in their organisation 3 are NHL calibre guys, so I highly doubt they'd take Neuvirth, but I agree on the idea that he should be shopped around.
Sam Morin played 15 games last year, and will miss up until Feb. this year, so I'm not sure he has much of any value at all in a trade at this point in time, but it would be great to bring in another right hand shod defender that can play in the top 6 consistently.
Morgan Frost was one of the most improved players in junior hockey last year. He and Giroux put up the same amount of points as 18-19 year olds in junior. I think at this point in time he and Myers are untouchable players.
MacDonald was an assistant captain last year, I highly doubt he gets bought out, but I understand the feeling of finally wanting to be rid of such an embarassing contract.
Putting together a package that included 2 or three of either Sanheim, Hagg, Rubtsov, Lindblom, Strome, Aube-Kubel, Vorobyov, Allison, Vecchione, or Martel, with a depth player and a pick or two I think would be much better for the organization.
That being said, the Flyers already have two great offensive defensemen. Why not try and find a right hand shot defensive guy, like Tanev, Hamonic, Pysyk, Murphy or Stone?

Thats right. I was just playing around. Frost is unbelievable. I would love to see Tanev with Gostisbehere as a pairing. That would be nice.

I think that the trade would have to include a umcoming d-prospect, like Snaheim or even Provorov
