First of all, I didn't originally meant for a way to extend the osu! windows to many displays (kinda like Eyefinity), just to be clear. 
I was wondering, in terms of aesthetics, instead of playing in the "Duplicate" display mode (where the same display is shown in both screens), can osu! do it in somewhat similar to "Extend" display, where for example, there could be two windows, but you could change each windows' visual settings (size, eye candy, etc.). This feature is probably useful for local gameplays, where spectators can see the player him/herself play. Since I use a custom minimalistic skin, in my opinion, it may not be that visually attractive to some spectators. In other words, could there be a feature where in a multi-display setup (monitors, projectors, HDTVs, etc.), you can use your custom skin on your main screen, while the default (or other specified) skin can be used in the other displays)?
Don't know about audio, since HDMI is the only connection I know capable of video+audio IO.
Note: I am aware that this option can take a decent amount of resource to work, and only the right hardware probably could support this. Experimental/Optional is what I see so far for this.
