No. they are very different radios than Quansheng. Even if possible, the firmware is much different. (different CPU cores)
I have both the Baofeng UV-5R and the UV-K5(8). The K5 simply beats the pants off the 5R, more power, more otions, open source firmware that can be reflashed in minutes expanding and improving over stock. For $35,, buy two.
The K5 8 is the hottest ticket in the ham and scanner arenas in a long time.
Just stock it is like a 5 band radio from 136 to 600 Mhz, and receive down to 50 MHz. Pre canned weather and air band.
Cheap Chinese junk ? yep, but it works.
