Some ideas to make your podcast channel unique

Here is a good idea to make your podcast channel unique. I have seen that most of podcast channels have only 1 interviewer. This makes the podcast boring in most cases. Better idea is to have 1-2 friends with you and there should be multiple interviewers. It is more like a group discussion. Very less people are doing this way and thus you have higher chances of getting noticed . What you think about this approach ? Are you going to try this ?
