I always pictured Max Weapon as a power-up box that powered up all your weapons and gave them maximum ammo, just like jjgod without the invincibility. That's just my guess as to what it was originally supposed to be like, though, not a suggestion for what would be a good new event (it wouldn't be a good new event IMO).

Personally I'd just leave them nonexistent and save the JCS.ini space for completely new cool events later.

P.S. Jerrythabest: did you add a mod pattern jump function yet? =P

edit: oops offtopic thought this was the actual JJ2+ thread somehow
