Yup.  To arrange thigns so that delay slots instructions are actually
printed (even if they start a series of 2+ nops 8-).

Not that I know of.  IMO, that would be very, very undesirable in an
actual disassembler.  My view is that you want the disassembler
to... disassemble what's there, not creatively reinterpret it.  8-)

(In something that, say, outputs pseudo code that one could
re-compile, yeah, it seems like a reasonable thing to do... which
sounds like what you're doing.)


Gotta wonder "why do you ask?"
