The answer is probably. Since they are home resort points, MS will typically allow members to swap out expiring points for non-expiring points, especially when the points come from a new contract that has been added to the membership.
Once you close, you would call MS and ask them if they could "reallocate" the points to use the expiring ones. Of course, if you have borrowed points as part of those reservations, those than not be returned. But, any current UY points you free up could still be banked.
I think the biggest problem would be making sure that you leave yourself enough time to buy, go through ROFR, close, and get the points in to your account in order to do this. Resale takes about 2 months from start to finish.
Good luck!!!
