When you deposit your HRC deeded week into HPP, it is essentially the same thing as converting your HRPP week into CUP points as you're giving up your guaranteed week/unit to exchange to another Hyatt property - except your points are on the HPP side of the fence in lieu of the HRC side. You can exchange into HRC properties via HPP points - however I don't see much of an advantage in doing that with HPP as you can already do that with your current HRC ownership.
The wild card in the exchange game is the wait list - is there one common wait list (HRC & HPP) or are there two different wait lists (1 for HRC and 1 for HPP). I haven't seen/heard a clear definitive answer on that - its possible that there isn't a simple answer to that question as there could be two different lists for the first 6 month period and then a combined list for the second 6 month period. Based on the one 2020 HSH prime time reservation confirmation with HPP points that I know of, I'm now thinking there are separate lists initially. I say that due to the fact that the prime time HSH HPP reservation confirmation came 51 weeks prior to check in. Since that HSH HPP confirmed week is a highly requested prime time, I'm certain that there were HRC wait list requests for the week - however the HRC wait list did not get the confirmation. The thought is that a hybrid owner deposited their deeded HSH prime time week into HPP - and that deposited week went to a wait listed HPP owner in lieu of a wait listed HRC owner as the week was still in the HPP priority period.
A positive with exchanging via HPP is the flexibility to select the check-in day and reserve single night's or less than a full week. A negative with exchanging thru HPP is that your $13k poorer due to the buy in price. Based on the HSH prime time week being confirmed to a HPP owner, it now seems the really big negative for you in trying to reserve Maui, Siesta Key or Breck through HPP is that they are not in the HPP program. So the odds of a successful exchange would drop dramatically as you're waiting on a unicorn to appear - a Maui, Siesta Key or Breck owner who also owns HPP to deposit their prime time HRC deeded week into the HPP program - while it's possible that a Maui, Siesta Key or Breck owner will give up their deeded week by depositing into HPP, it's not probable in my mind.
We need an HRC owner to attend a Hyatt Sales Presentation and drill deep into the HRC/HPP wait list topic - and don't let the sales staff side step/double speak on the answer. Any volunteers??
