Jim,
I know! I agree completely. The Atlas station is such a weird structure too, with it's strange roof pitch, dormers, and shake shingles, small footprint, and rather homely appearance that I've never really respected as a depot. Where in the world did it come from? I highly believe it's full of excellent fodder for kitbashing though! It's an excellent canidate for that. Unfortunately, 95% of the ones I've seen are unpainted, poorly constructed, or just plain ruined by novices.
AMB Laserkit has been awefully good about releasing SP and ATSF type stations with the detail deserved as far as standard designs are concerned. The SP type #23 and my favorite the type #22 depots are made by them, and ATSF standard depots of all sizes are manufactured by them. The problem is that they're not all that affordable unfortunately.
I heartily believe that we could use an affordable kit, perhaps one that comes with extra details to turn into a wide range of prototypes, like prototype specific detailing for locomotives. Instead of, say light packages for diesels as a prototype option, you could get prototype specific doors, windows, and architectural detail to go with your kit.
For example, a simple clapboard depot could be, with additional details, a C&O station with additional decoration under the eaves, and exterior wainscotting. That same depot could be an SP depot with different signboards and architectural detail.
