I did an experiment to import a LunarCell heightmap into Bryce as a 4096x4096 terrain in order to create an actual view of the planet surface. This is with no modifications to the surface(erosion, photoshopping etc.) The texture map is also the color map generated by LunarCell. The water is all Bryce and not altogether true to the original map. This is my most promising effort to date, and I still see a lot of problems. A 4096x4096 map of an entire planetary surface is very coarse and the 8-bit heightmap created by LunarCell exhibits serious stairstepping. Also it's surprisingly easy to tell that this, "planet" is flat. I'm looking forward to firing up TG2 and trying this again. It should help realism enormously to map this onto an actual sphere, and I could use a separate fractal function to add small scale detail in the foreground.
