I really hope I've misinterpreted your intention.
Or more practically, a smart loader than could select a kernel image based on arch and auto-detect to load the correct image. I don't really think it matters much what mechanism is used.
What makes more sense is to pack multiple segments for different processor architecures into a single executable package, and have the loader pick the right one (the NT model). It could be used for SMP and non-SMP images, though, as well as i386, i586, i686, etc.
