Yes, that is the BEST way!!
If none of the pups normally wear muzzles, then it's best not to start when you first get them together. Having something new on their faces/mouths may make them nervous and may send the wrong signal to the other pups!
Keep in mind... good meeting behavior for dogs are to greet one another side by side. (head to butt) Not so much straight on. To a dog, that is the least threatening greeting posture.
(Learned that by reading the book "How to Talk Dog" Lots of good things in there!)
I wish you all the luck in the world!!
