Go for it! Although Buster & Maggie still are not "best friends", I think they would be sad if the other one went away. When one of them needs to go the vet, I usually have to take both of them. I wanted to walk them separately as Buster has had training and Maggie has not, she cries and whimpers and my husband will call me to come back and get her. They sometimes cuddle. I think the older Maggie gets, the better it will get. They have good days and bad days but when they are having a good day...it's too much fun!!!
