Interesting but unlikely (by KC):
The fatal flaw in your proposal, interesting though it may be, is that it matters not one little bit what a buyer may have (over)paid a developer in the original purchase. That purchase could still be nearly worthless a week (or a day) later in the open resale marketplace.
Plenty of people are entirely willing to GIVE BACK their ownerships FOR FREE. For example, over 30,000 people have successfully applied to Wyndham's "Ovation" program since 2015, receiving absolutely nothing in return (except an escape from any future obligations), so why would Wyndham (or any other developer, for that matter) actually have any motivation or interest in helping people to recover any money from their original grossly overpriced purchase? It's a corporation, making business decisions, looking out for (and ONLY for) its' own financial interests, with no particular concern for their "customers". Sad, but true.
