Owning the exact same head sculpt twice?

I came to realize that I have a doll that I just like so much more than all the other ones (incidentally, this one was also my very first). That got me thinking: What if I just buy the exact same sculpt again and use one of my existing bodies as a base. Kind of like twins, except that the body and resin color are vastly different (I will also have to match one of the heads to tan resin). I don’t know why I never thought of that option before lol. Still, just thinking about how my collection could and most likely will look with those two makes me giddy with excitement!

Have any of you done this before? Do you have them as identical twins or kind of like siblings? Or do you have even more than two? And have your feelings toward that sculpt changed, for the better or the worse, when owning more of them?😊
