Yes, they are (the full author lists are printed on the respective mod pages as well as in the README, and I'm the project lead for both) but they'll stay separate, even though I do understand where you're coming from.
In part it's because of the different pace of updates (the banter packs, while infrequently updated, are still a "work in progress", while the flirt packs are done but for the occasional brainstorm) and in part because of the different types of content. There are some people out there who for whatever reason are strongly opposed to the flirt packs, and I'd hate for that to keep them away from the new banter content as well.
