I think the technical name for those is “one arm up, one arm down walks.” 
Dan John calls them “cross walks” here:
They can be a little confusing at first, and don’t expect to use the same weight in both hands.
As Dan John might say, try it for a while and then you tell me.
But yeah, if you ease into it and don’t go too far, too heavy, too soon, you should be fine to use some kind of carry as a regular finisher.
I vote yea, provisional that you consider tweaking things depending on how you’re feeling (reducing intensity or frequency if needed. It’s accessory/conditioning work, after all.) Farmer’s walks can definitely toast your grip and overhead carries will work all those smaller support structures of the shoulder and upper back.
