4 x CAKIR may be not if side by side placement is the only way.
But SOM-J has a stowed width of 480mm.
CAKIR has a diameter of 275mm .
4 x 275 = 1100 mm
2 x 480 = 960 mm.
If they can find 15-20cm more width inside the IWB then it is possible (after all as we have full authority over the plane, it is up to Baykar engineers to see if they can find the space) .
But otherwise 3 x CAKIR is achievable as you pointed out.

There is a lot of space there under its belly. I hope they have made it available to be used by the IWB s. When it has a 10000lbf engine it should have more MTOW capability too. Also wing area of KE is substantial, and should give it good amount of lift.
PS. Additionally, you don’t have to place missiles side by side. If space is available you may stack them on top of each other.
Also not to forget “sidekick” mechanism of f35-A and C versions.
