I wish it were that easy. While they may look like the right choices, the reality even within the software is another thing. Anyway I've been adjusting CMYK values in the MX document and have reached the limits of my hardware, and patience. To my eye the below sample looks darker but comes pretty close when photographed.
MX printing with CMYK of 184.108.40.206.
AI printing with same CMYK.
EDIT: Just for laughs. This is how many tries at getting the color closer I made.
