Ok, so without either pup being RWRP and assuming you want the Position 2 combination to be hum-canceling, then you have two options with those pups.
First, before describing the two options, i need to explain the reason for why special action is required here. In order to have hum-canceling when two coils are combined, one of the two must have a different magnetic polarity from the other (North vs South) *and* it also must be wound in the opposite direction from the other. Next look at this pic that shows the magnetic polarity of each of the four coils in two typical humbuckers where neither is RWRP.

Note that if one wants to have the two inner coils active in Position 2, there will be 60 cycle hum because the two inner coils are the same magnetic polarity (North).
*If* one of the pickups was RWRP, the inner coil of that pickup would have South magnetic polarity and there would be no issue.
So, for two pickups where neither is RWRP, there are two options:
Option 1. This is my recommended option out of the 2, FYI. Wire the coilsplit on the Bridge pickup so that its South coil is active in Position 2, and then also reinstall that pickup in the mounting ring so it is rotated 180° - in order to physically move that South coil to the inner position. I looked at pics of Juggernaut pickups and saw that each coil has screws, vs 1 having slugs and 1 having screws. So visual/aesthestic impact should be neglible. Should also be neglible if you have covers on your pickups. However, if you have the version with Misha Mansoor's custom image printed on the pickup cover, I can understand this rotation business being a concern.
Option 2. You or a tech you hire could partially disassemble your Bridge pickup to get at the magnets that sit at the bottom and flip them upside down, which changes the polarity of each of the two coils. There is some risk (not large, but some) that you may damage the pickup if you are not careful in doing this. You can watch how-to videos on Youtube about this and determine if you feel comfortable doing it yourself and/or you feel comfortable having a tech do it.
Option 1 can technically be done on either pickup, but I am recommending the bridge pickup in this case just because of the other pre-existing wiring complexities involved with the Neck pickup due it needing to do parallel-with-itself mode in Position 4.
Of course, if hum-canceling in Position 2 isn't important to you and/or rhe idea of living with some hum is ok compared to what you deem is too much hassle requirdd in the options above, then we can wire the guitar to split the inner coils as-is for Position 2 and you will just live with the hum that comes with doing that. You are going to have hum anyways when you have your Bridge coilsplit by itself in Position 1 and Position 3 as it is already.
I guess another option could be to acquire one RWRP Juggernaut to replace one of your current two.
Let me know how you want to proceed.
