I agree on waiting for the actual outcome. I will hedge my bet on a Chinese system.

Wouldn't that depend on the choice of AESA radar? Maybe the choice of a radar may take the weapons package into consideration. I.e. The European radar might be chosen because of the weapons offered with it.
My take however is that they will remain with China. A European rada/weapons package...
I think it might be a materials strength/rigidity and weight issue. I suspect rectangular section tanks might need thicker/more rigid design than cylindrical ones.
For the same amount of materials and stress levels (internal pressure), the rectangular tank will deform before the cylinder...

Are we talking about something similar to this:
I am making too many assumptions now.
I assume the guys shoe to be 300mm/1ft. On my screen that is 40 pixels. The bomb is 428 pixels. That is 3210mm. However the bomb is further away from the camera, so it is longer than 3210m
The Mk83 is 3m long. A Mk83 with a REK would be longer. I would therefore expect the kitted Mk-83 to be twice the height of those guys. I think that bomb+kit is about 2.5-2.75m long.
I have little to reference for pixel counting but it looks on the larger side than a Mk-81. However this is difficult because of the kit. And also the Mk81 and Mk82 are not very different in size;
I an thinking if they would ever use the REK for CAS? I believe it is not meant for that.
I guess it is about protecting the plane and launching 2 or 4 bombs you increase the chance of destroying the target.
