Hey, piece of advice if you're planning on taking on the JJ2-source code:
Instead of focussing on implementing new gameplay-modes, focus on implementing some sort of scripting/plugin-support that will allow the user to modify things enabling them to e.g. create new party-modes.
Thus, when someone creates a new party-mode other users only need to download the plugin and install that. If there's an update you'll only need to update the plugin and not the entire main-JJ executable.
Also, keeping one main version of JJ (v1.25?  ) avoids confusing. Imagine everyone creating their own version of JJ2!! AAAAARRRGGGGHH!!
BTW If someone is to tackle on the source-code, update some stuff like the music-/sound-engine while you're at it. Don't y'all hate it when you've picked some music and JJ2 totally scr*ws it up? And how's about fixing some of those notorious B.U.G.'s?
