From Calico Hills, you can loop over Kraft, over New, and over Redcap, then down the back of Redcap, and come out the way you went in. There are some scrambles in the slots E of Calico tanks, but I'm hesitant to recommend them as the routefinding is really tough.

White Rock Hills Peak is good too, but the routefinding is tough.
If you start in Calico, going up and over Redcap, then looping back through Gateway Canyon can take some time and give a wide variety of scenery.
If you have a GPS and can load tracks, I can narrow routes down a bit; but a lot of routes have obscured sky, at least part of the way. Jim Egan's SE route up White Rock Hills (on SP) gets you to a point where you can traverse up to some cairns, and there are descriptions (elsewhere) for the trek from there. I have lots of tracks on maps, but the scale of routefinding is generally much smaller than what you can resolve on a contour map.
If you go to Redcap from Sandstone Quarry, you can traverse east down the back side then over to Calico Tanks and back on a trail. That route requires one very sketchy section, so you would need a bit more detail.
