This is very interesting, it looks like it's coming along.  This looks like it can be converted to Cycles without too much trouble once it is completely worked out.   I don't know your progress with Superfly rendering, in particular, using Cycles, but there might be problems with super bright ambient illumination as per your setup.  Mesh lighting can cause considerable render noise leading to long render times just to clear it up.  In my judgment, relying exclusively on ambient illumination as the primary source should be reconsidered, and use a low ambient flame with an inverse square point light emitting blackbody illumination.  IMO, that is the better way to use the candle flame in a scene.
