My feeling is if you bought a J-Custom, put the pickups you like in it. Complete the instrument. Life is too short to dwell on pickups......
.......well, maybe they should be dwelled upon for a little while. Do you want a Super Distortion and Liquifire in your J-Custom or would it just be convenient? (Convenience is not a bad thing by the way.) Regardless of the answer, you have two guitars you need pickups for which means it might be worth trying something you have never played or heard before. Take a risk because pickups matter much less than we think they do. I would put all aftermarket pickups in the "good pickups" category because I have never swapped out stock pickups for aftermarket pickups and thought the stock pickups were better. In my opinion, pickups, especially the bridge pickup, need character and purpose. The X2N is a good pickup. It has character and purpose. Distortion is its purpose. The Evo 2 is a good pickup. It has a mid-range snarl with the high frequencies chopped off (quite literally). I like the Evo (another good pickup) better. In the neck, the Liquifire is a great pickup which is why I assume you bought one.

The PAF Pro, Air Norton, and Mo' Joe are all good pickups. (I think the Mo' Joe is a bridge pickup but I used one in the neck position and it worked well.)
You know what I played for a long time? The Tone Zone. The Tone Zone is a good pickup but it really lacks character. Its purpose is to be a safe pickup that isn't too hot but just hot enough to be fun. You may love the Tone Zone and think all of this is crazy. (You may hate the Tone Zone and think all of this is crazy too.) I was told the Tone Zone was a good pickup (which it is) but I was never told why. "Versatility" is probably the best one-word description I can come up with. Now, compared to the X2N, versatility is certainly an advantage, but compared to the other pickups I named, versatility tends to make life kind of boring for that guitar. Eventually, I switched to 7-string guitars, sold my 6-strings, and made up my own mind about the Tone Zone.
Whatever you decide, pickups are not "life and death." Pickups are like the color blue, we all have our favorite shade/hue of blue, but in the end, they all work. You can actually buy several Dimarzio pickups from their "custom shop" like the Double Whammy and Dual Sound (I think). I would love for someone to try the Double Whammy unless someone steps in and says it is the worst sounding excuse for a pickup ever made. In that case, I would advise against it. Otherwise, take a risk. Your guitar will still sound like a guitar.
...And that is roughly how much "dwelling on pickups" a person should do. I realize there are other pickup brands but the scope of this post is limited to Dimarzio. Lundgren's would be cool and different. They actually have a lot of character now that I think about it........................
