Intel has a compiler that allows one to declare things are big or little endian and then things work.  A certain large router vendor used it to port its software that was big endian only at a very deep layer to Intel x86...

Linux marks things as beXX or leXX and uses static analysis to prevent mixing.

There's a lot of prior art for the committee to choose from.
