I think it would be great to see UAA and UAF in a Canadian league.
BCIHL would be a huge step down in quality even for a team barely making the WCHA playoffs.
I think Canada West would be a good landing spot for them but there would be huge changes in scholarship structure, eligibility rules, etc. Not to mention, a lot of the roster could/would be likely to transfer to another NCAA team with the discontinuation, on paper at least, of the hockey program in the NCAA's eyes.
Travel would still be less than in the WCHA obviously but Canada West spans east all the way to Winnipeg which is still over 2000 miles/4000 km from Fairbanks. The good news is that the games not played against other Canada West teams are localish lower level BCIHL/ACAC teams. Occasionally teams will play NCAA teams in exhibitions but those usually come with at least a little monetary incentivization.
Even if the University Alaska combines athletics into one program, they could pull off hockey in Canada West if U Sports was willing to grant them affiliate membership but that all hinges on if the University/Universities even want to bother.
