No, that's a great idea!
I had misunderstood what you said about the failure. If the perforated tube is what failed then your solution should be the fix. That area sees the most heat and by being perforated it has more surface area, which will in turn becomes more vulnerable to the heat. The 321 stainless perforated core in the mufflers I have received back with melted sound deadening meterial were turned blue from excess heat. They most certainly would have failed if aluminum.
