Housing/Inn suggestion: Battle theme changer

The battle themes are boring. Especially ARR's. So I suggest adding a housing item, much like the Orchestrion, except it serves the purpose of allowing you to change the battle them for certain areas.

First of all, you can't change it for sub-zones; only the whole zone. You can't give northern Thanalan a different theme to Southern Thanalan, for example.

Second of all, you can only change the normal battle theme. No fate theme, no Levequest theme, so on, so forth.

Third, you need the Orchestrion roll. You can't just change it to whatever you want.

What do you guys think?
