Personal wish would be a glamour system for LBs, from LB1 to LB3.

So on Samurai I could have some different versions of attacks for LB1 and LB2 where I use a katana, and then for LB3 I could have Hien's LB3 from Gymlit Dark.
All of these would just be glamour so function/damage is still the same, and could change just LB2 if I wanted to keep the old LB1 and LB3 versions.

Would let people customize how their LBs looks like.
