I think a re-release of ExtendedDancEPlay 12-Inch through Record-Store-Day will not so desirable, as some other rare issues incl. more rare songs, because it is very common and easily to get.
Encores will be a good idea, like the 2-7-Inch Set with the Demo-recordings.
But it is my opinion, only.
Also cool will be a new edition of On The Night Live 2-LP-Set, or rather Golden Heart or Sailing to Philadelphia as vinyl-versions.
