Sounds like it could be possible, but it isn't going to be easy. Aluminum really likes to run so it is best to have it laying flat, especially on something thicker like a casting. A MIG is DC where the TIG is AC for aluminum and they are quite different. I wouldn't imagine it would cause an issue if you unplugged the ECU, but I would be a little leary.
If this is just a sealing piece and is not stressed, I would honestly try JB welding it. I have seen that stuff hold up to some amazing stress on some of my buddies' cars/mudders. I wouldn't try that if there is a bolt or dowel in the piece that is broken though. I would talk to John, he is probably the best welder on here now, but I don't know if he does much aluminum.
