I'll have to look to see if I did this with Lodima at the same time. What I experienced was a warming of tone. I want to warn you that Kbr is a restrainer and as the amount got much above 6ml/ltr the prints needed additional exposure to compensate for the added restrainer in the developer.
I have so much Azo/Lodima I've decided to put together a notebook. The notebook contains images all made from the same negative but using different emulsions of Azo/Lodimia paper in different developers. Early on I noticed how much different Azo looked when developed in Dektol, Amidol or Neutol WA. I figure some day I'll have an image that just screams for a particular tone. I expect the notebook to help me decide just what combination of paper/developer will fill that need.
I'd encourage you to complete the work with the various amount of Kbr, you'll learn a lot.
Good Luck Henry,
