Agree with you there but with the new live action Pinocchio coming out this year, the show becomes 2022 relevant again. But it would need updated projections, pyro and even spot light integration.
Disney is unlikely to alternate shows as it can create turmoil in the scheduling based on favoritism (could you imagine if they alternated HEA and DE).
All of that being said, Disney's recent surveys to guests suggest that HEA is just simply going to return, perhaps with Main Street projections (I don't think they'd actually modify the storyboard to add new films).
If Disney were to return Wishes, they would be surveying guests with a vague question like "How interested would you be in updated versions of retired shows?" or something along those lines.
