Double barreled riser?

I was watching a video of the double vortex in the riser and thought "What if..."

Interesting idea.  How would this riser variant affect the 3T's of Time, Turbulence, and Temperature?

I can clearly see how this riser would divide the double vortex and confine each side to it's own lobe.  

Hard to say what benefit would be derived v.s. any downside.

I had considered a vacuum formed ceramic fiber riser constructed in something of a honeycomb layout where at full burn there would be multiple vortexes all going at once.  I was talked out of this idea, as previous attempts by others at double risers showed a proclivity for the fire to take one path or the other, but never both at the same time.  

I hope you try it out and let us know what happens.
