picking up foragers is a little difficult. it's not like getting swarms. you could try putting a couple of hives in the same place the pollinator had his, but it's probably not worth the bother. then you would have to merge then into your hives...and for what? they are at the tail end of their lives anyway.
as for the breed, it makes no difference. as long as you are not breeding queens in that area, what he has in his hive wouldn't matter. even if those workers were to join your hives, there wouldn't be enough of them to change the temperament of the hive.
