I see plenty of problems with it in a serious campaign..
I'll list a few..
1) TV-chefs tends to have a fairly high recognition factor, meaning they are easily recognized by people seeing them on the street, being a media star and a shadowrunner seems like a certain path to disaster.
2) Having your own TV-show is a pretty big deal, but it also means a lot of responsibilities i.e., regular schedule for filming said shows, preparing for the shows, explaining to the tv-network why you have a black eye or a broken arm for next weeks show - the network expect you to be professional, show up, do your job etc, this will mean saying no to shadowrunning jobs, leaving your team in tight spots to go film, and don't even get me started on your contacts all more or less knowing you are also the fancy celeb tv-chef which means any one of them less than 4 loyalty are bound to tell/sell someone that information sooner rather than later.
