Different BladeStorm spell art

This is a lil hard to explain but, what I want is, is change the appearance of the bladestorm's tornado to look like the "Water Tornado" model you can download on this site. I hope it doesnt involve model editing =/. Please help.

you could try setting the unit's vertex color to blue with triggers:
trigger #1
event:
unit start the effect of an ability
cond:
ability = Bladestorm
action:
set BladeStormUnit=triggering unit
change triggering unit's vertex color to 0, 0, 100, 0

trigger #2
event:
unit finishes casting an ability (or ends channeling i dunno)
cond:
triggering unit = BladeStormUnit
action:
change triggering unit's vertex color to 100, 100, 100, 0


if it doesn't work, you must edit the model...

You'd have to edit the model if you wanted it to really be like the water tornado. The bladestorm is a perfect cylinder, and is grey. Another way would be to edit the spell itself and make a buff that attaches the water tornado to the origin point of the blademaster. Those two and triggering are the only ways i can think of to get it to work.
