I have never seen the inner wing pylons carry AAMs though, only fuel tanks and larger ordinance or bombs. I also find it hard to believe the two front fuselage pylons are both support two heavy medium range missiles like PL-12 to say nothing of PL-15, while also clearing the landing gear without protruding in front of the intakes too much. I think these two pylons are reserved for smaller bombs and pods only while the rear fuselage pylons are bombs only.
Look at this picture. The SRAAMs can give an idea how long a PL-12 would be. Given the position of the pylons, a PL-12 will probably either block the landing gear or disrupt airflow into the intakes. I'm not sure how much that'll really affect the intake's performance though.
I think it's probably far more realistic for the J-10 to max out at 6 x mraams total or 4 x mraams + 2 x sraams. Inner pylons are probably not compatible with AAMs. Unless I'm mistaken there, in which case, add 2 mraams and drop fuel volume.
