Hmm...
King of the hill could be done because of the getpos(cn) function but I think maps would have to be made specifically for it because how would you know where the hill is? Also each map would have to be hard-coded into the script because I would have to know exactly what coordinates counted as the "hill".

As for juggernaut It could definitely work. I could make it so that cla can only have one person on it (the juggernaut) and everyone else could be on rvsf. If what you're thinking is the same as what I'm thinking, I would put whoever killed the jug as the jug and whoever is the jug for the longest amount of time at the end of the game wins. I think I'll get started on this.

As for disarming and planting bombs, I have no idea how this would work client side.

I'm pretty excited if either King of the Hill or Juggernaut actually works out! I'd love to help you SplatZ, but I know almost nothing about scripts and mods. Though I can always help test, along with my fellow clan mates.

The Juggernaut being the only player on one team sounds like a good idea. When someone kills the jug, basically the killer and the jug switches teams.
This works great; as you all probably know in Juggernaut, one can only gain points by killing the Juggernaut (or as the Juggernaut, kill anyone else).
This team system will prevent non-juggernauts from fragging other non-jugs to gain points, as all others besides the jug are teammates. If you do so, you'll get -1.

Anyone have suggestions on how the jug is buffed? In video games I have played:
-extra damage
-extra hp max
-cannot pick up pickups, but has limited auto-heal
-gains health by killing
