I don't think we need some silly show. I think they need to do what they originally announced they would do..have an organic, immersive experience throughout the land with stormtroopers policing the streets, vendors trying to sell goods, spies lurking about, innocent citizens being apprehended for not obeying minor laws, some bounty hunters making cameos, and some renegade coming in starting a little trouble ending in a shootout.
That is immersive and fun and we shouldn't know when to expect it.
Anything else lessens the area and it doesn't need it. It's already Space Adventureland (in space).
