The idea seems perfectly valid, however.. just one note..
So I love Stargate SG-1
Make sure your players do as well
Thats one of the hardest things as a GM, sometimes your idea of fun, is not shared with the players - and without players, no GM

Personally I could see a few metaplanes scenarios being fun, but I wouldn't base my entire campaign around it, I think it would get rather repetitative, watching all the SG-1 episodes is a bit like that, its the same over and over and you won't have funny one-liners to make up for it unless one of your players have a comedy talent

Of course it would also have a huge impact on your shadowrun world if this was a regular occurance, access to new resources/information would put a corp wayyy ahead of others, which might lead to balance issues, or the Corporate court getting antsy, which could lead to fun runs against that corp, so as a background story and a few runs, sure, and then let rest of the campaign focus on the fall-out from a corporation dealing with such.
