Have you tried Portra Endura paper? It is discontinued, but should still be available fresh.
The problem with skip bleach processing is that it also totally jacks up your contrast. You gain more controllability by inserting a controlled b/w development step into the process (called ENR), and then bleaching. This lets you control how much silver you wish to retain. I have done this only with film, but I imagine it could work with paper as well. Even with a mild ENR, though, your contrast and color still get a little wonky.
Digital scanning would be a good option if you just can't get it any other way. It will cost you to get a nice scan and Lightjet print, however.
If you must stay 100% analog, you can also alter contrast and saturation by copying.
