So would anyone actually be willing to take part in this? We can have more than one genre fused in the mix. We gather some people and we decide on the flow of the song and then we each map our own sections later on for a marathon beatmap (maybe around 4 to 5 stars so that it's not extremely difficult).

We don't have to all work in the same environment though it would make things easier. I personally use FL Studio 9. We can also possibly limit ourselves (in terms of the sound fonts and instrumentation we use) so that the music can flow nicely. I think it would be a little tacky to have a break after each section (and any transitions like fading out should also be avoided) so it's important that the music is continuous. Also, it should go without saying that all music has to be completely original and specifically made for this project.

We can first decide on the genres, instruments used, and how the project will be managed (for example, what programs will be used and the arrangement of musical sections). Then we can decide on the BPM, the length of the song and all its parts, and so forth. Everyone should contribute the same amount of music, so we should design it in such a way that everyone can participate equally (including stuff like breaks).

We don't have to go for a ranked map, although that would be a nice thing. I'm not sure that everyone would be that committed, though. Even if not, if we have enough people to work on editing the map to make it meet standards, it is possible that we can eventually go for a ranked/approved map, although it's not something to think about until later.

I'm sure something like this has probably been done in the past but I haven't heard of anything recently. What do you guys think?

I can give a try at mapping, but keep in mind that I'm still new.

When would this be taking place?

I'd be willing to start as soon as we're able to find enough people to contribute original music. For a marathon difficulty, I'd say we need at least 6 people (including myself) to participate. I will wait and see what others think before I edit the main post with anything about positions. Mappers/modders are always welcome. Even if the people willing to contribute are natural mappers, it doesn't hurt at all to have a few extra hands for that. Especially in terms of modding/feedback.

Ok.

So do we need people creating original music? Because that seems like there won't be enough people contributing music to make a standard length beatmap, let alone a marathon map.

I thought I'd give it a try anyways. We don't need much music, just about a total of 2 minutes from each person would be fine (making a minimum of 12 minutes if we can actually get five more people). If we can't get that many people to participate, however, I'd still be willing to collaborate with just one or two other people to create something.
