If you don't think shipping the guns to yourself in Alaska is an option, I would make friends with a US Customs official. The usual drill is to get the 4457 filled out in advance and have an official verify that you possess the guns before he/she signs. Be specific enough so that extra sets of barrels, etc. are described. This is done a couple of guns at a time or you should make an appointment.
As for the Canadian side of things, the forms required are as described above. If you are obviously moving house (maybe towing a trailer), be honest and say these are your hunting guns which you are moving to a new residence. Try not to cross the border at peak times. Have the forms filled out in advance and the guns ready for access if requested. Be sure you have the US paperwork in order and ready to present. It will almost entirely depend on the luck of the draw as to which personnel you find.
I also print out the applicable regulations and have a copy with me.
In my experience, all processes depend on serial numbers. If there are different numbers on actions, barrels and forends, record them. If you have that information from a third party, either the person from whom you purchased, a gunsmith, or other, so much the better.
