Well yes, but not as how you would like it ;-)
The fat binary will have to be recognized by a magic that actually
differs from normal elf executables!
If they are the same, binfmt_misc can catch them, but then the interpreter
(which has to be non elf of course) has to manage every elf binary. At
the time the interpreter is executed it has no chance to reject the binary
and continue processing other binfmts.
Better modify binfmt_elf or ld-linux/ld.
