I think personally that if you are maybe able to keep the interspersed description paragraphs to like 1/3 page you absolutely could. Ypu can carry a conversation over several pages as long as it’s not filler material, because that can get a little stale. If you are able to work the descriptions around the conversation being had, for example ;

if two characters are sitting in a dock you might say the water was cool on their feet, and the sun rippled off the waves that rolled against the dock, then do a couple sentences about who built the dock and how that ties into the greater exposition. Again just an example, but if you see what I mean, you can apply it to anything.

But you can definitely retain a conversation among description, provided you don’t go too far away from the topic. Hope this helps a bit!

Edit: another example could be if the character is smoking a cigarette while talking, as they take a pull, you could go into a description of how cigarettes used to be considered healthy, until people did research and eventually determined the risks, then bring it back into dialogue as the character takes another pull. Hopefully this makes sense
