LE New weapon mod effect help/request

[ORIGlN]

An idea for a special weapon effect like bloodskal blade except without the energy projectile. The concept is a short katana that can extend it's blade and retract instantaneously. The blade would extend 10 meters after a power attack in a slash similar to bloodskal projectile except it would be the blade itself and hit anything behind or inbetween with whip like animations but follows a straighter path, excluding immobile objects (walls trees etc.) it would not affect any companions/followers however. Another addition would be to use a power attack and right or customizable hot key simultaneuosly to initiate a thursting animation but when the activation keys are released would make the sword extend and impale whatever is in it's path (holding the animation keys longer will increase the range of the extension regular activation extends something like 10 meters) idea comes from bleach's zanpakuto . I would like to know how to achieve this at it's not as easy as simply making a texture for a weapon. Anyone may use this idea for this mod with permission if it is needed. If anyone would like to help me or join me in making this mod that would be greatly appreciated ^^!
