I doubt that's possible - a bytecode program just can't run fast enough to do
the timing for the IR commands, on either brick.  The NXT can only manage it
because it sends them over a slow comms link to a HiTechnic IRLink sensor, then
that handles the actual transmission.  The only way the RCX could do it with
it's built-in IR LED is to code the functions into a replacement firmware, as
with Bob Kojima's BrickOS example:

(...) Dick Swan's replacement RCX firmware also does not support directly manipulating the IR led and it doesn't support microsecond timing control. Both of these features would be required in order to send the IR messages to a Power Function or R/C (...) (17 years ago, 4-Feb-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics)
