I've had mine for a while and sadly haven't gotten around to using it much yet. Just small 5x7 test prints, BW, and on cheap office max "professional photo paper" glossy, they actually came out pretty great. At first they were super dark, and I was a little mad, and figured ok, more time spent on profile settings in PShop etc, then an hour later they had dried nicely and lightened up.
For what its worth Im planning on ordering some of the Ilford inkjet paper to see how that goes, maybe thats something youd want to try? Theres the Epson papers as well :

Though Ive never tried them.
If you find any info on converting it to a BW setup, Id definitely be interested in how it goes, for now Im just using the stock Ciara.
