David Beamish has a page listing "writs in acceleration":
There won't be any other cases where they were subsequently created a life peer. However, there may be cases where the holder was subsequently created additional hereditary titles after inheriting existing titles from his father. I couldn’t see any obvious instances of this from a quick skim of the page, though.
One slightly similar case that comes to mind, although it doesn't involve writ of acceleration, was the 7th Earl of Longford, who was created a hereditary peer in his own right as Baron Pakenham. He subsequently inherited his father's titles, then was created a life peer following the 1999 Act on the grounds that he was a hereditary peer of the first creation (i.e. 1st Baron Pakenham).
Other ways to become a peer could include a law lord under the
Appellate Jurisdiction Act, although I doubt any of these were also made a life peer under the 1958 Act (some will later have received hereditary peerages).
There are also Irish and Scottish peers who were subsequently given GB or UK titles, etc.
