Realistic flames question

I have this idea that I havn't seen yet and want to know if anyone else has seen it, (pictures would be even better). Shade Shift Realistic flames inside the Standard outlined flames. Sort of like flames inside of flames but in a shade shift.

ive seen them done in apearl so at diffret angle that you look at it it looks like the flames are moving is that what your talking about

yes but have that inside the shape of a standard shape flame.

i was it on a bike at bike show in Maggey Valley, it looked alright

I have seen the real flames inside of more traditional flames, but not with "shade shifting" paint. Frankly, it was just to much. I have never been a fan of mixing flame styles, but that is just me.
