Make a new ICC profile for your fine art paper and PK, adjusting driver parameters so they make sense for the paper in question. You might start with Epson Semi-Matte (a "Photo Paper") as a media selection, but I'd expect you to require adjustments in platen, paper thickness and perhaps ink limits. I can make no guess about the canvas settings but I'm sure others here will have insight.
Whether this will save time effort and money, by the time you are done, over making the nuisance PK>MK switch will be interesting to see.
Good luck,
