Is that a possibility given that the current producers (Bialystock and Bloom? - jk!) want to close the show someone else might step in to take it over, or has this never happened in the history of Broadway? Not to go too off-topic, but this happened with ROCK OF AGES when it moved to the Helen Hayes. The original producers were set to close it at the Brooks Atkinson when different producers came in who wanted to continue running it at a smaller theater. They in effect "purchased" the show from the original producers, moved it to the Hayes, and it is still going strong.
Then of course, there are all the times a nonprofit Broadway show makes a commercial transfer, but I don't think that's what you're talking about.
