Hey MacD,

When I was looking for a larger SSGT insignia to do the same thing in my little brother's memory couldn't find one. But, the folks at Semper Fi Mac offered to make one. As I recall the price was pretty reasonable.

You might give them a shout. Apparently casting custom pins is a regular thing for them. The stuff I did buy off the shelf was good quality.
