For what it's worth, cat personalities definitely evolve over time. The fact that you have standoffish kitties now doesn't mean that you won't have lapcats this time next year.
We adopted a young adult cat from the shelter thinking she was an affectionate people-cat, but it turned out she was just in heat. Once that passed, and then after the spay, she wanted nothing to do with us. She would swipe and hiss if we tried to touch her or play with her. It was distressing, for sure. That was three years ago, though, and over time, she became more trusting, more interested in us, and in the last six months or so, downright affectionate. She sleeps at my shoulder every night, and drapes herself over my arm as I sit at the computer. We still can't touch her belly or pick her up, but we've come such a long way that I'm going to qualify it a success.
So hang in there! Let the kitties come to you, but do every manipulative thing you can think of to encourage the trend. If you tend to spend your evenings on the couch, under a throw blanket, perhaps, dab a little feliway on the blanket. You're already comfy and warm, and with feliway, you'll smell comforting too. It'll be that much harder for the kitties to resist you! If you've got room in your house to run around, try dragging a ribbon behind you. I think a game of chase, more than the feather teaser, is a good way to make the cat associate "person" with "natural cat entertainment".
