Sorry, there never really was a precident for recording replacement cast members (except for Brooke Shields doing re-dubbing in of her parts for "Grease" and "Wonderful Town", and a handfull of other recordings like Pearl Bailey in "Hello, Dolly"), so we are not going to be getting any new (official) recordings of Grease
