We don't have anything like that planned, but do plan to do an  
assembler and disassembler.  The disassembler (for x86-16/32/64) is  
iterating on review comments before it goes in.  The assembler is  
currently being built out and will initially support macho.   
Translating X86-32 to X86-64 sounds tricky but it could probably be  
built on some of this infrastructure.
