Sure thing, but let me ask this.  Can Poser turn surfaces into light emmitters using light emission maps?

Now that I'm done work for today and have some time off I figured I would take a closer look at this question.

I watched this tutorial on making Emission Maps for Unity.

Turns out it's very easy, as an alpha with color being driven by settings or as a color map. With this in mind I created a quick color map in Photoshop...

I then attached this map to a one sided square prop and used an Emission Node hooked up to a CyclesSurface root and rendered in Superfly... here's the result.

Yes, Poser can utilize Emission Maps.
