Heartbroken over losing the buds, I decided to move the plant out to the greenhouse over the summer.  It did pretty well growing three to four feet of new vine, and another peduncle, but there was no sign of budding up.  When I brought it back indoors in September, I put it along with some other tall Hoyas into this tent seen below in the video:

The tent with LED light made all the difference in the world; the plant finally started budding up in a big way on one of the new peduncles that it had put on over the summer, and these buds made it to maturity and opened in early November.  Below you see the plant in its full glory:
