Of all the airplane projects that are now ongoing in China ARJ-21, C-919, Y-20, J-10B, J-16, J-20, Z-20 and the J-31. I feel that the J-31 is the only one that's unneeded, unnecessary and out of place.
Unless the Chinese are looking to engage in a High/Low mix J21 or what ever you want to call it would fit then the Larger J20 being the Hight the J21 being the low.
