projectile helper assistance

[Flowrellik]

Ok. I am messing around with projectile transparency *again* and theres a question thats been bugging me.
Is there a way where you can create a second projectile over the main projectile but does nothing but act as sort of a mask over the existing projectile, giving the projectile a more solid look while still maintaining transparency?

Nah that would be a helper then.

helper or not I wish to know how to make it possible.
