Framing and Mosaic Wizard - Expansion

I have a number of images where I would like to add some frames around the main image and make a wider field mosaic. A typical example might be the the Veil Nebula where I have an Eastern Veil image but would like to get a mosaic of the whole complex. It would be nice if there was a way of loading my existing image into the Framing and Mosaic Wizard and then adding panels around it, so that I could be certain that I would end up with a good mosaic.

Would that be a difficult thing to do, do you think?

You can, for the most part, do that now. Have a look here:
