@GODUCKS First, I hope your brother and your family is okay and doing well! Second, what you are packing into the 1 lb bags should be 100% fine, that won;t be a problem as you can use a large stuffing tube. Where you might run into an issue is with the stuffing into the links. Since the meat has been sitting after it has had the seasoning (especially the salt) mixed in it will start to set up and become a little more difficult to deal with. Mixing it again will help a little but be careful not to overdo it, your meat right now is probably going to start extracting proteins very quickly. Now, that isn’t the end of the world or anything, it might just give you a different texture than you are used to from a breakfast sausage. All in all I think you will be fine!
