Noble attempt but it will never work unless you just live inside your siege-proof base and trade amongst yourselves. If you ever need to warp to a market, CoV and other rogue killers will just attack you for sport, heads, or because they are bored.
The golden era is fun to read about, but the problem with most aged servers is that the players who have been around forever – and haven’t been bored and quit – have a major advantage as they’ve setup xp farms around spawners, villagers, etc. Even the occasional death is no big deal because they have dozens of chests full of gear, enchanted books, and everything else they need. The only thing keeping them playing is the twisted thrill of jumping deckies or otherwise ranked but still less powerful, not-geared-for-battle players.
Unless you require all of LE to get Captain and one-button marco their no-delay warp, the rules you outlined above will just bring fresh meat to the slaughter.
Lastly, don’t underestimate the treachery of these veteran pirates. Many players have alts and they will just join LE with an alt and then tpa inside whenever they are in the mood for a culling.
LE’s rules would only work on a fresh server restart, and even then, only for a short while.
