...How would you want it to sound?
Don't worry about any real-world complications or any of that shiz. In a perfect world where SY is coming back on top form and they're about to head into the studio..what do you think you'd want them to make?
Personally, I think the time's come to revisit the sonic comedy / pop culture jabs of the past, ala Ciccone Youth and Mariah Carey and The Arthur Doyle Hand Cream. There's something super snide and kool about fusing that style of explosive guitar energy with a very detached and bored look at modern celebrity culture.
No more songs about old punk band frontmen, no more allusions to hippy beat poets, and no more songs about being a transient state of love and/or loss. Throw together wicked new tunings, a shitload of obscure alien-sounding pedals and crazy effects to create fun, lively and most important of all, endlessly blaring noise.
