Brandi -
I use my tights for both biking and for walking - and I don't want a chamois when I'm not biking. So if I'm biking in cold weather, I always start with my bike shorts and top them with tights. Oh, and if it's really, really cold then I wear bike shorts, knee warmers, and tights.

I suspect that you'll be a lot happier with both your shorts (with chamois) and tights, as opposed to just using unpadded tights.
