If you were in zone 9 there would be little tricks that could help you, but zone 8 may be stretching it. You can certainly try it with a few tricks and see how it goes.
In general, if you keep cacti dry in the winter they tend to handle the cold better. A mineral based soil that drains water well is a must if you want to attempt outside overwintering. Also, do not water at all in the winter. The plant will be dormant anyway so this won't hurt it.
You can also put these plants close to your home or other heated structure. The small amount of heat that escapes through your insulation can benefit zone 10 plants in danger of freezing.
Finally covering the plants in the winter will help keep the frost off of them and increase the probability of their survival.
