Is it possible to add another style tab where we can choose if we want to wear or wear not another lantern ring? Just like Kyle Rayner and Guy Gardner? Make all ring colours available, this could please some of the players who have been wanting to play as something other than will, fear or rage, some would still prefer a new lantern powerset but this would be enough for me.
DarkVisor answered your question. In further detail DC Comics (who is owned by Warner Brothers), has a contract with Daybreak that gives certain freedoms to use their intellectual property for the game. The IP would be anything DC Comics invented or created. Daybreak has to pass just about everything by DC Comics for approval before it goes into the game. Unfortunately the Lantern Corp inspired powers are attached to power rings and those are color locked for reasons that should be obvious.
