Code rouges castle chests and make it a new money maker

[Generousguy]

would be a fun money maker and imo i think opening 1 chest should give 5x more xp then osrs, and should be around 10k pkpt an hour looting them. Would be a badass new rebuild money maker/new way to get thieve xp. I also think it should require 84 thieving just like osrs. why I think it should be 10k pkpt an hour(at max efficiency) is because it is not very afk and is a very dangerous way to make money. I also think it should give you hard clues at a rate of 1/1000, meaning it would take on average 4 hours to get 1 hard clue at max efficiency. What do you guys think of this idea?
