This sounds very familiar to me. I have developed a few tricks to deal with multi-lens panoramas. The first thing you need is lots, and I mean lots of good control points. That's why I wrote the woa plugin, which warps the images, looks for CPs and then unwarps their coordinates. This usually gives me such an even spread and good quality of CPs, even between images from different lenses, that the optimizer produces very good results. The next plugin which I find very useful is the crop-cp plugin, which looks at the crop area of the panorama (as set in the preview) and throws out all CPs either inside or outside it. This allows me to throw out all CPs which aren't really crucial for the match (forground, for example - let the stitcher deal with it best it can). Once I've lots of CPs in useful places left, I optimize for 'everything but translation' and also do a photometric optimization. Then I can proceed to stitch each set of images separately, and I have to do the final composition in another tool, as well. Lots of work, but, for example in mountaintop 360 degree panoramas, the extra crispness around the horizon can be worth it. BTW - a panorama head is a good thing - if most of my photography wasn't done somewhere in the mountains I'd sure carry on all the time, and they aren't even dear. I've built my own which was fun and it does the trick, but out in the wild I rely on a walking stick and a technique I've evolved over time which works well enough for natural subjects. Having tools like enfuse deal with a situation like the one you describe would be very welcome, hence my proposal. Especially the layering is annoying for me, because in cinepaint I usually get annoyed very quickly by how awkward everything is (maybe I've just not done it enough...), the gimp only does 8 bits, digiKam just isn't quite there yet and I can't accustom myself to fotoxx either... but at least on Linux I was able write the plugin interface and the plugins I need most.
