Is it possible to combine 2 types of panels?

Well I bought panels from a vendor but with a little delay inbetween. I noticed that the mapping is not matching. I allready figured out the mapping. My plan would be to use 6 Panels of the first charge in 3x2 (192x64) + a bottom line with the new charge (192x32).

I thought there might be just an array which stores all LED-Adresses. Would it be possible to just exchange adresses there? Or would it be possible to give the bottom line another panel mapping?
