[Event?] New weekly event / event for weekend

I am not sure if this is possible but i would like to see double drop event.
A event that when something drops it will drop not 2 of the same but trigger 2 drops from that drop table.

Lets say you finish a small/lair dungeon and it will drop:

Without the event:

Small dungeons
2 gears / some glim / maybe a gem box if not on elemental world / some key fragments.

Lair:
3 gears / some glim / Gem box / some key fragments.

With the event:
Everything will trigger twince so.

Small dungeons:
4 Gears / twince as much glim / double the chance for gem boxes / double key fragments.

Lair:
6 gears / twince as much glim / double the chance for gem boxes / double key fragments.

So it would be like a gem box day, half of the adventure day, it would be like the old days of double key fragments, it would increase the chance for better gear.

And it dont need to be a full week, something like a super saturday may be fine.

Let me know what you think about it. :)
