Redirect to download another file. Maybe?

Question

Samsung

I don't swim much in this topic. But it's interesting to know if it's possible. What I will describe below is perhaps my imagination.
There is a samsung smart tv K series. As you know, all the younger series were loaded with custom widgets without any problems. But not this series. Here the only thing that can be done is to change the dns, as a result, with the replacement of the widget. But the widget that it replaces is also necessary.
So. Is it possible, when trying to download a TV widget from the market, intercept its packets and give out your widget that lies on FTP?
