You may not be using the right primer. The Kat Von D primer is actually made to go with the Kat Von D Lock It Tattoo Foundation, and it's a decent one - it's water-based, and silicone/dimethicone free, so it's oily skin-friendly.
If you still have issues with oiliness, try the Becca Ever Matte Priming Perfector too - it's the exact same formula as the old Urban Decay De-Slick in a Tube, and it's the Holy Grail of primers for oily skin - good luck!

I experienced separation with the Double Wear as well, but have not experienced that with this foundation. I use a good primer and lightly set it with a translucent powder and it lasts a long time for me, even with the recent hot weather. I'd say it's worth a try! Maybe try a sample first just to be sure.
