Layering / stacking of effects ?

Didn't find a thread for this, so thought I'd throw it out for opinion. With the number of weapon effects out there (and more on the way, I'm sure), I thought it would be interesting to be able to lay one effect on top of another, and was wondering if the programming made this possible. For instance; place both "Ebony" and "Awakening" on a weapon to get more of a smoulder effect. This would be a nice way to perhaps boost the sales of the old "classic' effects, as they could be layered together to create various colour schemes. This would also open up plenty of customization options, and would lead to a lot of more unique character designs. Any thoughts?
