Mixing Both Aluminum and Magnesium Rims (+Praga Dark 28)

I’ve read that magnesium rims and aluminum rims affect the kart setup differently, but what happens if you were to run both at the same time (i.e. magnesium in the front, aluminum in the rear and vice versa)? Will there be a significant handling disadvantage compared to running just 1 material? I run at a low grip track with Bridgestone YDS tires and I got a narrower set of rear tires to help with grip. They are of different designs, so I believe they are different materials. P.S. Does anybody…
