If you are inspired only by the End dimension and shulkers, you should create something pretty similar to the ShulkerWars, which is Minecraft PE PVP-map.
There are four teams. Each one is locked on the island and the only way to escape it – create the road to the next island. Some of them may be guarded by shulkers, but there you can get better items and blocks. Speed affects your winning chances so bad.
ShulkerWars is the map, where team-play is the most important thing. If your are slow and if you are arguing, you just waste time, because you need to get the as more items as possible. You may ask where is the PVP itself? The battle starts right where you meet other team. Main objective is to remain the last team standing, so there will be no individual rewards, but still it is great way to have some fun with your friends.
