Well, it does say DCS A-10 vs Falcon 4, which means the Warthog vs the Viper.
I may be wrong a few years down the line when DCS World matures, and I hope I will be! But as of this moment, with the current state of both sims, my opinion is that BMS has a lot of that "potential" already covered, except for that annoying terrain graphics. I love me some low-altitude ingress screaming over the terrain at 500 knots at 300 ft AGL, and that brings that ugly terrain right up to my nose. I miss my DCS terrain and my lovely GAU-8, but the A-10 is a one-trick pony while the Falcon is more "all around" hence my recommendation.
As for the OP's question, well, the "panels" themselves are not really interchangeable since the side console layouts are different, but I think if you have the switches wired properly, it would be easy enough to un-screw the relevant switches and transfer them to another panel with a different layout.
