New year's event ( earlier heroes of the month)

I know this is something moderators are already working on, but I had an idea that would work either for those players that don’t get too lucky with pulls or don’t want to spend money.
Basically I thought about an event “wheel of fortune” like for the 31st of December: there would be a circle divided in sections for which corresponds a previous hero of the month and an indicator that shows which hero you’ll get; you will be able to spin the wheel by using gems (about 500-700). You can spin it for max 2 or 3 times (to be fair to those players who don’t spend money to buy gems) but won’t get the same hero twice.
