They're tough as all hell up here too - but the biggest issue might be north easterly winds, so just make sure the camellia(s) have a bit of protection if the new garden's exposed. Pick the right spot
Don't know how Magnolias cope with it though - have never grown them.
I'd agree with Ceres and 8000wf about taking cuttings rather than the main plants/shrubs though.
