Not really. Normal trap-hacking depends on replacing the function address
associated with a trap identifier. IR is implemented as a system library.
This means that rather than just identifying the function by trap id, the
OS multiplexes the library reference number *and* function trap id to jump
to correct function.

other ways?
Yes. You can hack the SysLibFind trap and look for someone trying to load
IR, then load your own version instead.
Hope this helps.
