On a side note... a new set of hilts that are not remade ones with a fancy animation would be nice as-well.

Black Core-White

Like the one Mandalor has in the Clone Wars cartoon

Silver

A magenta expertise crystal.

Sunrider's Destiny :P

Rainbow sparkles with a glitter trail.

Purple in general, just cause its purple doesent mean it has to be..... purple, know like rareity wise, I want my Sith Inq to be able to have that saber color

Really, just stick to the SW universe colors. I think I read somewhere, that back in the early days of lightsabers, there were a more colors than just red, green, blue and the rare purple but they became increasingly rare due to like... overmining or something like that. Do you really need that laundry list of crystal colors? Really... Lime Green? Where does it end? Fire-engine Red? Eggshell White? Seafoam Green?

Oooh that's be nice...

Purple crystal (I hear it's in game, but doesnt seem to be end game) and a pink crystal!
