Rhythm Heaven characters in WarioWare?


Diamond City Mayor
Diamond City Leader
We've already seen quite a few of them added to the series, usually as background characters in story scenes and microgames.

So what's the future of this? Will more Rhythm Heaven characters get added in future? Perhaps even as main characters in the series?
Well it happened the other way around so maybe? Rhythm Heaven is pretty much dead right now so I'd totally welcome it.
