Option B would be even worse in that regard as they would be all divisional playoffs in the 1st two rounds. At least with the 8 division format, I assume they would have a conference format with the division winners being the top 4 seeds and seeds 5-8 are whoever has the most points in the conference after that.
If they went with 8 divisions, I could see it looking like this:
EASTERN CONFERENCE:
Division 1: Boston, Montreal, Ottawa, Toronto
Division 2: Buffalo, Columbus, Detroit, Pittsburgh
Division 3: New Jersey, NY Islanders, NY Rangers, Philadelphia
Division 4: Carolina, Florida, Tampa Bay, Washington
WESTERN CONFERENCE:
Division 1: Chicago, Minnesota, Nashville, Winnipeg
Division 2: Arizona, Colorado, Dallas, St. Louis
Division 3: Anaheim, Los Angeles, San Jose, Vegas
Division 4: Calgary, Edmonton, Seattle, Vancouver
