It is a very winnable situation. It's just one that years of neglect have forced their hand into not even attempting.
At the very heart of this issue is the entire resorts lack of capacity. The "need" for the Hub refurb is born out of the ever increasing load that the MK has to pull. As a result of it, every ride and attraction in the MK has to pull even more weight than ever before. Things that use to be a "cherry on the sundae" like parades, fireworks, and meet-and-greets have been pulled into front line duty for the entire resort and are now "manifest destiny" guaranteed to all guests with a FP+ reservation. But, that of course is why they have to carry the weight now. If you can't fit everyone into the rides and attractions they want to experience during the day and the offer of a return time for an attraction that people don't want to experience (like Stitch) isn't enticing people, offer them up a reservation for one of those "cherries" I mentioned earlier. Of course now, you need to guarantee those cherries happen - so you can't take them offline.
Look, I completely understand that any ride or attraction going offline impacts peoples vacations. The sad fact is that WDW has used the excuse of not wanting to due refurbs, updates, and enhancements under the guise of wanting to make sure poor little Sally-Sue and Jimmy-Joe's once in a lifetime visit isn't tarnished for so long that attendance increases have gotten to the point where MM+/FP+ was created out of "necessity" and now they can't pull things offline to do even necessary work (like the current situation with PotC).
There is no reason why the parks in Orlando couldn't be run the same way the parks in Anaheim are if the parks had more ability to share the capacity load. If you are not familiar with what is going on with the ramp up to the 60th Anniversary for DL, take a look at the Disneyland Resort forum. Currently, Sleeping Beauty Castle is behind a scrim, World of Color is offline, several rides and attractions are down and the world <pun intended> on the West Coast is still spinning.
For use as a particular barometer, tune into our very own Mike S's thread for his current 1st visit ever to DLR:

He's hitting DLR at its worst and let's watch what his impression of the place is when he runs into the perfect storm of refurbs. My guess, is that he will still come away with an outstanding time.
The situation in Orlando is such that if you pulled a similar load away from any of the parks, things would fall apart quickly because there isn't enough meat on the bone remaining.
The solution to WDW's problem is simple. Return to the method that has always worked. Grow capacity at a rate that exceeds demand. Add new rides and attractions that guests want to experience and prune away those that they don't want to. The shame of an attraction like Stitch or Imagination or don't shoot me, Maelstrom, is that they should've been plussed or pulled out for something different ages ago.
Instead, we get the nuclear wasteland that is the Hub with it's FP+ corrals.
