They have released a double feature of the Dead End Kids plus 1 or 2 other titles. Angels With Dirty Faces and Dead End were released along time ago, so a lot of the Dead End kid titles are out already.
East Side Kids would be a big problem. I know some of the series is in UCLA but not sure how many of the 20+ titles are in good condition. Most of this series seems to be in worse shape than the Bowery Boys. That said I would definately be on board for an East side kids release. If they do 12 films a set like the Bowery Boys they should be able to do the series in 2 volumes.
