You have an idea, and it needs to be discussed publicly. What do you do? Start a podcast, obviously! I’m not here to tell you what to talk about but I will say this: It needs to be engaging and produced in a way that makes sense. Good content is always engaging, no matter how badly recorded it is. That being said, good production can make content even more engaging.
Finally, why make things complicated? There’s nothing wrong with a very simple, no-frills structure, especially if you have a catchy hook on which you’re seeking to rely heavily. This seems like a fairly popular structure for hip-hop tracks in particular.
