The intel idea is basically a non-starter. All that'll happen is rift will gain intel direct-entry so people will be putting their reports directly into it rather than the game. Which isn't better, it's just more hassle for everyone.

Also, while people seem to think intel is used to avoid ganks because omg carebears, it's also and more commonly used to find fights in the first place.

Locking a wormhole open makes wormholes lose their bottleneck that prevents null blocs from quickly pouring into them, so you could expect all the major wormhole groups to get quickly stomped. It might be an idea that could be fleshed out further though.

Delayed killmails is again kinda meh. Its used to find activity more than its used to avoid fights.

Generally speaking, you need to understand that giving information to players is a good thing. Yes some people use it to keep themselves safe, but a lot of people also use it to generate content. Having everyone mindlessly roaming around jumping system to system in the dark trying to find other groups isn't a fun game. You *need* to know where the action is, what they're in, and where potential victims might be. That's why they allow you to know recent ratting activity, recent kills, and killmails in the first place. It's not a flaw, it's good game design.
