Instead of a temporary stone to trade gold for pcoins, ocoins, etc., why not a slot machine similar to the one in Luna Bank that awards powerscrolls. Make the stone award rare items like one use Tokuno dyes, or maybe some of the pcoin or ocoin deco items, even some of the hard to get stealables or doom drops. The big prizes would be rare to win but I've seen several players drop loads of gold on the chance for power scrolls on the slot machine in Luna.
The "buying buffs" is a great idea - consumable and desirable.
Paying for certain spawn options in the PVM room sounds cool, too.
Of course, the King could always take a census and have us paying taxes! LOL Ugh, forget I said that!
