Sterling JP60 pickups

Hi
i am new member here, but long time MM user. i had a Axis Super Sport, Silhouette Special.
Now my main axe is Luke 2 and newest one is mystic green JP60, that is incredible and on par with my Luke.

Now i have a set of Transitions pickups and still trying to decide whether to change the original pickups.
And add a push push to split coils in mid position (and maybe also put the neck humbucker in parallel with the switch in neck position for a more single coil sound without hum).

Suggestions on stock pickups vs transitions? any specs of the stock ones? of course i am a huge fan of Lukather.
