It would be quite the same.

Ran no Jidai, the well-known japanese mod is already in very good way, you should look at their forums.

If you really want support from the community, you should try to make something new, but still faisaible and enjoyable. There are too many mods projects, very few have been completed and of those in developments only a part would see a final release. It's very hard to do a good mod.

If you got some nice skills in modding, it would really help the community to join another big project. Just look throughout the forums here and on TWC.
