Thanks for the replies. I actually meant to delete this thread yesterday upon leaning about the gmax layering thing over the weekend. Gmax and I don't really get along.

However, since I decided to start out with just one of my local airports, I'm finding that the low-res photoreal actually blends with the default pretty well. If I were going to cover a really big area, I might learn how to do it, but low-res is good enough for now. I'd love to post it as a freeware add on when I'm done, but there would be so many permissions to acquire that I doubt it would be possible. I have to say though, with Fs Earth tiles, ADE9X, SAMM (the tool for making static ac from flight models in your hanger by Don Grovestine), a whole host of library objects, and the Autogen annotator from the FS9 SDK, even I can make great looking scenery! I'll post a few shots as I get closer to being finished.
Thanks again!
