So I redesigned the league.
The ones requiring the most explanation are:
Martian Manhunter: If you're a shapeshifter... why should your original shape resemble anything else at all?
Batman: All that money and the mantra "criminals and cowardly and superstitious lot" I think Bats could do a better job at making himself look like a scary bat creature.
Cyborg: In this day and age why is his original design so clunky? In this version he has access to his "ark": a large container of upgrades and additions he can equip if need be.
