All of this is meaningless because it's too far gone. The clans and CPs have long left, and the ones who remain will keep playing with the changes you propose or without. Better ask for fresh server so that there's again an influx of people and these content updates can happen. And mean something.
Yes and yes. Time to get a new server rolling as so many people are ready to be back on classic.
Broader suggestion:
Create a catchup classic server that would be seasonal, e.g. 2 years and merge it back to the stable one (dion) over time.
