I think basic economics suggests that TacticalStache is probably right, the way to go would be to split the set in to the "Alphas" and "Ergodox Mod", then add the mods for standard keyboards. At the very least it might drop the price on the Alphas for the Dox.
Also, I'm interested. I'd prefer them with legends, but I want two sets of caps for the Dox I'm building, one low, one high, and this seems like a good high profile set (unless someone does a KT profile set).
