What obscure character that will probably never be seen again would you like to see get a book?

Original 7 soilders of victory

This ^ DC original Severn Soldiers, predate Seven Samurai, Magnificent Seven, and DC own Seven JL founders.
Yet DC has completely forsaken them as ever having been a team?
Although with some updates, with all the team building in the CW Universe's Team Arrow, as far as I know they've never even hommaged Arrows actual original Team.

As much as Oliver Queen himself and Speedy(Arsenal) have been modernized for a contemporary audience, all can easily be updated, we've seen Vigilante. Crimson Avenger DC's first masked hero has gotten updates and legacy characters in Jill Carlyle (make her his new "wingamn"), and Lee Travis himself easily translate to a modern street level hero. Stars and Stripes have been updated, through Star Girl, that leaves Shining Knight, who honestly just needs to be reimagined as he was always a modern hero descendant (maybe a cop), who is granted and wields (powered by) the supernatural ancient sword.

Morrison's team was fun, but can easily take a different name; actually JL8, as he originally intended.
