I obtained a profile that seems to do the conversion OK. Why do
you need to create your own? I use the following profile
which also limits the ink density to 240%:
SWOPcoated5_240.icc

Any conversion from RGB to CMYK will involve some shift in
colors. Not all RGB colors can be expressed in CMYK.
But you knew that already, right?
