Why not two characters in esf. A normal Trunks and a future Trunks. one with short hair and the other with long hair. normal Trunks should be for the people who like to play with a fast character and the future Trunks is slowly but with strong attacks.
future Trunks:
normal
ssj
ussj
perfect ssj
and normal Trunks:
normal
ssj
ssj with more speed and power
ssj2
(I'm not sure what forms normal Trunks should have)
