I have also given thought that the Kamchatka and Kodiak bears appear very cave bear-like. Any chance this lineage could have a touch of cave bear?

Both Cave bear and Brown bear descended from the Etruscan bear, a native bear species from Europe.

A group of Etruscan bears that migrated to China had became a new subspecies, and this new subspecies eventually evolved into the Brown bears.

So they are sister species within the same genus, so it is very likely that they can produce the healthy fertile offspring.

Other Cave bear species such as Ursus ingressus and Ursus deningeri were most likely the subspecific populations of the classic Cave bear Ursus spelaeus. Reply
