Armchair Imagineering here only of course, but the more I think about Country Bar Jamboree (posted in jest yesterday), the more I like the idea. It'd be a way to preserve / honor classic attractions while appealing to Millennials/Gen-X's love for themed entertainment and specialty cocktails.
The same could be said for Tiki Room or other attractions supposedly on the chopping block. These F&B venues could be added to resorts, instead of at the MK where alcohol is still(?) a touchy subject. Let's be honest, all on-property resorts could use a Trader Sam's equivalent.
While sit-down dinning venues are forced to encourage quick table turnover, I'd imagine WDW lounges would rather you to stay for a few more drinks. It's no surprise that Oga's Cantina has become a breakout star of SW:GE (the $75 Rancor Tooth souvenir beer flight board has already sold-out for the season per WDW*NT).
I for one am ready to boldly enter the age of hyper-themed Disney resort bars.
