Ok fellas, update:
I took out the JB and the Jazz and replaced them with my Duncan Invaders I had once in my Ibanez, turns out they sound surprisingly good in it. It's always astonishing how much wood affects tone, as my RG has a Basswood Body and an all Maple Neck and the guitar sounded horrible with them, the Alder Body of the Dinky seems to make a huge difference.
However the Jackson has now nice grit, lots of low mids and bottom end to it and still cuts well. Leaving me with another Idea: the Ceramic Warpig.
There's a video Keith Merrow did, comparing the Warpig to the Invader and the Aftermath to the Distortion, the Warpig seems to be similar to the Invader, just clearer and tighter:

Ceramic Warpig - Similar to the Invader, just better. However I'm still afraid it might get a bit too flubby (as the lows of the Invader are already intense, it's labeled with Lows: 7/Mids: 8/Treble: 4 on the Duncan Website:
http://www.seymourduncan.com/comparetones/view/55 and the tone chart of the C-Pig says it has more lows than mids) and that it might not cut like the Invader. I don't know why or how, but the Invader cuts brilliantly allthough it has so much lows, I let my bass player riff on the Jackson, went outside our practice space and you could still hear the guitar perfectly without loosing any important frequencys through the Walls.
Aftermath - Very tight, very clear and percussive with nice mids and not too overbearing highs like the JB tends to have them. Then again I'm afraid it might sound too dry and "djenty" for the kind of music I play
Painkiller - For the same reasons as the Aftermath, but eventually not as "dry"? Then again not sure if the mids could be overkill.
Please help me out guys, hope I could explain my desires a bit better. I attached a pic (in cr@ppy quality) to show off the hopefully soon to be complete family :D
Cheers
p.s.: CanadianMetalhead, thanks, good to hear that the C-Pig would fit. Still I'd like to hear some more opinions ^^
