Trace, hazels will strike from cuttings pretty easily, but you may have missed the season for doing this. Another thing that you could try is grafting. If you already have or can get access to the hybrid varieties you want, they're one of the easiest nuts to graft with a simple whip and tongue, cleft, or bud method. Rootstocks could be any robust variety that sends up lots of root suckers.
If you do graft hazels, do it low down and mark the branch, as you will want to prune out suckers later when they develop.
[EDIT] One thing to add: Graft onto root suckers in place, let them grow for the entire season, then dig them this winter and plant them out. You'll get better results than if you start with freshly dug rootstock.
