Unpopular Changes YOU Would Like on the Game

Are there any unpopular changes you would personally like to see added to the game, even though you know it would never pass a poll or would be widely disliked?

An example I have is ​regional banks which​ would feel more appropriate, with perhaps questlines to add interconnectivity. It would help new areas feel more exotic and perhaps force you to use more local resources unless you want to ferry resources and items dozens of times before unlocking interconnectivity.

Bank Notes would now be marked by which bank they were issued by (like "​Iron Ore (K)" for the bank if Kandarin, and only redeemable if that the other bank has an interconnectivity agreement.

Example: Let's say you primarily used the Bank of Misthalin (starter bank, works in Lumbridge, Draynor, Varrock, Edgeville, ect.). If you entered Kourend, you would have a completely empty bank in that region until you somehow work out a deal between the two banks.

I know it won't happen due to spaghetti code, polling, and it being major change to the core of the banking system, but I think it would be fun do you have similar ideas you know fundamentally just can't or won't happen?
